The real cal howard said:
Because if Goku hasn't adapted to getting jumped after fourth straight years of martial arts, what makes you think the self-improvement of 45 minutes of fighting is going to change that?
Well for one, yes, Lucario has complete control over its own Aura so it can do that, but even then, why give someone an ability they've never shown? Why just assume Tupper just has a certain ability rather the vastly more likely chance of Goku letting his guard down, which btw, is a thing that nearly got him killed a few arcs back.

Because Master Roshi, the person who trained Goku and is considered such a great martial artist that even Beerus respects him,
believes Goku was using Ultra Instinct to keep up with Caulifa and Kale. Krillin, Tien, Beerus and no one else could believe Goku's ridiculous improvements as a martial artist with Whis outright stating Goku was sharpening his skills as he fought, similar to how he could improve in Ultra Instinct. Goku's leap in performance is so vast, so great, from when he fought Tupper that even Beerus was astounded and seemed to consider Goku using Ultra Instinct to be plausible.
Also, Goku went from 3-A to Low 2-C in those '45 minutes of fighting' so I honestly have no idea why you think Goku can't do the same in-regards to pure skill. It's quite clear his limits as a martial artist were also broken by using Ultra instinct.

Can you show us some feats to indicate Lucario can hide its life force?

It's extremely doubtful that he lack the ability to suppress his energy. He is a veteran warrior of the pride troopers, one of the absolute strongest in the entire multiverse and one of the 10 best fighters of Universe 11. Jiren, Toppo and Dyspo all displayed energy suppression abilities, IIRC and even Frieza, someone who has never trained before, could suppress his energy levels down to 1% of his power. The only people who lacked ki suppression would be Frieza's soldiers who had never received training in Ki Control like those that know Ki suppression.
Overall, it's a basic assumption to believe Tupper has access to suppressing his power when he is one of the 10 best warriors of his universe, when it's an extremely basic skill and when other members of his team have displayed the ability to control their energy output. It is a clearly established ability that anyone with half-decent training can utilise.
vastly more likely chance of Goku letting his guard dow
Not a chance. Tupper states Goku let his guard down.
which btw, is a thing that nearly got him killed a few arcs back.
Against a defeated Frieza, yes. He didn't anticipate a secondary person (who, mind you, is an ant to him) to shoot him in the chest. The only times Goku has ever let his guard down is when he doesn't anticipate other people to sneak attack him. If he is in a 1v1 fight, his defenses won't be penetrated.
Thisis Goku against Hit, an assassin from Universe 6 and the greatest warrior of universe 6. In a one-on-one match with no interlopers, Goku can handle Hit's invisible attacks, battle against his dimensional phasing and ultimately tie with him. So it's less that 'Goku lets his guard down' and more of 'Goku has blind spots when focusing on fighting a single person'.
Tupper only got the drop on Goku due to Goku already fighting the Pride Troopers, evident by the numerous pillars of dust exploding from clashes at the location Goku was grabbed and the fact that Tupper grabbed Goku from behind. Overall, your claims have no value when Goku is fighting a singular person.
