Well, if it's anything like the Jedi Knight series or Kotors as you level up you earn points to spend on talents, so if they go by that system it's possible to get your force grip skill high enough to do such a thing.
Then again, I know fuck all about this game except for how awesome it looks.
It does have a basic levelling system, yeah. It's obviously not a full blown RPG like Kotor but it's pretty equivalent to God of War.
Then there's the famous concept art/screenshot depicting your character force-crashing a Star Destroyer.
Yeah, I think it's safe to say that your force power gets good enough to fling an AT-ST.
