That's not quite right in theory.

There are two things that limit your pushing power, torque and traction. If you're limited by torque when pushing, then when pushing against immovable objects, you will draw a huge amount of current and trip circuit breakers. You can add more torque by changing gearing and / or adding motors, until you provide more torque than your wheels can ever exert. When this happens, when pushing against a wall, your wheels will slip. This is called traction limited.

Adding two motors allows your drive to become traction limited while running at higher speeds than a single motor.
