This is entirely possible, my dad was in a car accident with minor front end damage, the &^%$F# tow truck driver tied the rear end down so hard on the flat bed truck that he bent one of the rear trailing arms.My dad drove the car home from the collision shop after the repair for the collision damge was completed, and immediately noticed the car pulled to one side and needed about 10 degrees of steering wheel input to keep the car going straight, I took a drive and confirmed something was quite wrong and brought the car back to the collision shop.The owner of the shop was really baffled as he saw no damage to the front end suspension components from the minor collision, we then walked around the car and both him and I noticed immediately one of the rear wheel had a noticeable toe-out compared to the other rear wheel.The rear trailing arm was replaced at the towing company's expense.
