Would it make a difference, if a car was driven into a wall or another car with the same mass going exactly the same speed?

Yes. It depends on what the wall is made out of. Is it made of 16 feet of tissue paper or 1 foot of re-enforced concrete? Also depends on the car? is it a new car designed to bleed of energy via crumple zones or some 1970’s death machine designed to look cool?
Acceleration is a function of time, and soft things give more time for deceleration.
