Perhaps, but there are a few tactics up the Clan Leader's sleeve I know for sure would provide him an advantage over Terminator, such as disarming and observing/studying the Terminator. Now Yautja are also able to fool their foes/prey into believing they are dead by stopping their heart from beating, holding their breath, and remaining completely immobile until performing a surprise attack on their prey/opponent at the best moment. Only I'm not sure whether of not the Terminator's tech will pick up on this.
But as for disarming tactics (which are common in Yautja), this should leave the Terminator unable to attack the Clan Leader at range. Furthermore, the Clan Leader could utilize his shoulder cannon to target Terminator's weapons and blast them apart or out of his hands, thus leaving him unable to retaliate effectively at range. This can also be done with the Clan Leader's smart disc or shuriken.
Then for studying and observing Terminator, the Biomask of the Clan Leader will allow him to analyze and give a necessary list/descriptions of the genealogy, physiology, equipment, basic combat disadvantages & advantages, and neurological state and information of their prey and opponents in a matter of seconds. But since Terminator isn't an organic lifeform, the Biomask won't analyze anything dealing with organic matter/life, but will still grant full knowledge of what Terminator is capable of, his equipment, basic combat disadvantages & advantages, the fact he's a robotic/artificial being, physical stats (useful for informing the Clan Leader on what metals and tech the Terminator is composed of), and etc...:

^ Do note that there's more info in the scan, but I couldn't get an entire picture of the scans where they scroll down for more info and stats, but I didn't so I wouldn't have like 6 scans as that isn't really needed.
Guerrilla tactics come in mind as well, so the Clan Leader can utilize his superior agility against the Terminator, making him hard to keep up with and hit. Not to mention the Clan Leader can use the environment to his advantage, especially in a jungle environment, where the Clan Leader is aware of his surrounding, can find plenty of cover, hiding spots (especially hiding above the trees), and escape from assault with ease.
As for the advantage Terminator has in ranged weaponry, I guess you could say he has a greater variety of long range weapons, but then again the Clan Leader has several mid and long range weapons as well, such as the shoulder cannon, spear gun/sniper, assault plasma rifles, plasma pistols, plasma shotguns, net gun, small projectile blades, combi-stick/spear (when thrown), smart disc, shurikens, and etc.. But then again it's different since most of Terminator's weapons are of modern, human technology while the Clan Leader's weapons are of course,
alien technology, for example, the shoulder cannon alone which is more powerful than almost all human weapons.
Plus the weapons, specifically the shoulder cannon is supported by a targeting system which is 100% accurate (doesn't necessarily mean the blast will always hit its target, at least under specific circumstances) and can follow targets as fast Xenomorphs who have bullet dodging capabilities.
Onto CQC, the Clan Leader also has incredible knowledge in this area as well. In fact, Yautja have a martial art called Jehdin, which is something as best loosely described from Steve Perry to be as a fusion of Penchak Silat, Aikido, Kyokushin Karate, Tae Kwon Do, Bokator, Lucha Libre, Xilam, and other more complex combat skills desribed to be
superior to all martial arts on Earth. Even the lowest ranking Yautja have also been said displaying skills such as that of samurai.
Then another fact is Clan Leaders have perfected their skills in this martial art to the point a Clan Leader was thought and described as fighting a horde of Xenomorphs as if he was in a choreographed fight/dance with flawless movements. Plus fighting in a way described as superior to just about all martial arts and artists on Earth. What's even more impressive is the fact that the Clan Leader was still recovering from a broken back and ribs (due to being struck by a high speeding futuristic vehicle + massive explosion) yet managed to show off literally some inhuman level of combat skills.
Also, going back to experience, that is indeed an impressive amount of experience for Terminator, but I just don't think it's the same as the Clan Leaders since they not only have several millenniums of hunting/fighting experience and training... But what really separates their experiences is the fact that the Clan Leaders experiences are from
galactic hunting/fighting various
extraterrestrial species superior to humans mentally and/or physically, such as Xenomorphs and Space Jockeys (Engineers from
Prometheus). With that being said, I'd like to share with you a photo of Wolf's trophy room from
AvP: Requiem:

So as you can see, there are various extraterrestrial beasts and sapient being in the trophy room, even several humans, Xenos and Xeno Queens, Space Jockeys, and most interestingly Dinosaurs (Triceratops, Carcharodontosaurus, Raptor species, Duck billed Dino)! What's also very impressive is that IIRC, Yautja will only put beings in their trophy room if they were fought and beaten in an honorable h2h fight. Other than that, it comes to show that with the Clan Leader's level of experience, he's learned from numerous mistakes made and seen from distantly past battles against various galactic hunts an battles, as well as knowing the best methods of defeating all sorts of opponents no matter how different they are from each other.
Yautja are also highly intelligent and adaptable as well, as you should know that the Clan Leader being of the Yautja species, possesses intellect far beyond and superior to that of all humans. Then of course, Yautja are very capable of strategizing and planning too, and his technology (especially his Biomask as spoken before) will be very helpful in this fight.
Going back to your other comment on the shoulder cannon, the Terminator is indeed highly resistant to plasma weaponry, but then again it doesn't mean he's completely immune to it. So I believe it would just take a while for the Clan Leader to wear out the Terminator, and keep in mind that the shoulder cannon is powered by plasma batteries that last for a very long time, which for sure won't usually ever run out during battle though. So ammo isn't an issue for the shoulder cannon. However, the Clan Leader might just resort to his shoulder cannon if he realizes the Terminator is too durable to be taken out by other means.
For your point on the boiling acid feat, well the thing is the blue corrosive solvent Yautja carry is completely different from boiling acid in terms of their chemical components and corrosiveness. This is because I certainly think the blue solvent is far more corrosive than the vault of boiling acid, which Yautja can carry several vials of the solvent. Hell, in the scans, the Terminator may have made it out still functional, but he did appear relatively crippled by the acid so he may be more crippled by the blue solvent, who knows? But personally I find the blue solvent should at least incapacitate Terminator.
So lastly, here's how I see the Clan Leader defeating Terminator... First off, I'll clear up h2h combat, where if they're just fighting with bare fists, then they won't be doing anything to each other as both are too durable to hurt each other this way. However, the Clan Leader has the advantage in CQC as he's far more agile, tougher, and so far I think he's more skilled as well. Not to mention a Clan Leader easily defeated a tougher than average Xenomorph Queen with bare hands, and the only injury he received was a broken mandible. Although, the Clan Leader could perhaps damage or even put an end to Terminator with his molecular cutting melee weapons, such as his smart disc, as well as high tier combi-sticks and wrist blades.
In close combat, the Clan Leader's net gun should also be helpful in temporarily leaving Terminator unable to attack, giving the Clan Leader some time to plan and leave him vulnerable to attacks. If the battle is taken to ranged combat, then the Clan Leader could use his shoulder cannon, his other plasma weaponry like plasma pistols/shotguns/rifles, wrist guns, or spear gun/sniper. His best bet against the Terminator would be to use the shoulder cannon and spear sniper, as he not only can disarm the Terminator, but can wear him out and do damage as well. Furthermore, the shoulder cannon should eventually do enough damage to Terminator and defeat him if sustained long enough.
For the spear sniper, it will fire out tiny, barbed, molecular metal blades at a very high velocity that could pin a man's head or entire body to a wall and shatter concrete, which should pierce the Terminator's alloy structure and eventually do enough damage to destroy or cripple him. As for Terminator though, his ranged weaponry, I honestly have to say, either way should be completely useless against the Clan Leader as I said before, won't do any serious damage other than slit his skin an make him bleed without armor, which Clan Leaders are typically equipped with a full suit of bulletproof, Yautja created armor. Not to mention how agile the Clan Leader is, making him untouchable to his weaponry.
