As long as the rear wheels of the towed stayed in line with the coach track, you could do it. but when you need to make a turn you'll have a problem with the steering caster of the towed.
The tow bar does not allow the front of the towed to move side to side when the front wheels of the towed are steered. then the caster will spin the steering wheel out of your hands. When / if the driver of the coach were to turn the steering wheel of the coach, the same thing will happen.
pushing forward, no problems, the towed will track just like it does when being towed.
Since you are going to have to have the toad motor running when you either push or pull, I doubt if there is anything that will defeat the power steering and spin the wheel out of your hands. As you mention you do have to stay very close to being in line with the MH or you will lose traction. When we moved about 50 yards we did have to make a gradual turn to get where we were going. Making a 90 degree turn is probably going to take a pretty large radius so that the toad does not try to push the MH sideways instead of forward.
I did this with a Chevy HHR, front wheel drive. It might be entirely different with a rear wheel drive vehicle where the drive wheels are farther away from the tow bar.
