You really can't guarantee anything unless you have seen it.
Elizabeth Olsen's character also is hanging with his best friend and getting introduced to Josh Brolin by him. Her charcter is also encouraging him to search for his daughter and clear his name in this trailer. That also wasn't in the original movie. Seems they are fleshing out that getting revenge is a choice not the logical next step after his release.
That would be the logical thing to do if the villain is trying to set him up. Keep in mind he ain't seen his best friend in 20 years, who knows what his motives are. And honestly that's an extremely minor change compared to 90% of the trailer being damn near a shot-by-shot remake.

about the remake because it's so similar to the original:
