Ok, am going to word this differently, again.
The planes wheel's clearly have 2 different speeds. The speed in which the plane is moving forward, which I'm going to label as its static speed, and the speed in which the wheels are spinning, which I'm going to call their rotating speed.
If the question is
Imagine a 747 is sitting on a conveyor belt, as wide and long as a runway. The conveyor belt is designed to exactly match the
static speed of the plane (you can substitute the word wheels for plane here because the wheels, as part of the plane have the same static speed of the plane), moving in the opposite direction. Can the plane take off?
then you have a case.

then, you have no case, because the rotating speed of the wheels has no affect on whether or not the plane can move forward or take off.
