Hold a match-box car on a treadmill. Put the treadmill on slow, medium, and fast speeds. Push the car forward while the treadmill is at each speed. 100 to 1 you will use the same force each time to push the car foward. That force is enough to overcome the drag on the wheels. If the treadmill is moving at 200 mph in reverse, you would still only need a certain amount of force to push it forward.

The plane would take off...
I think that in essence the question is could you make the plane take off at a stand still. Which is no, you even stated the plane has to move forward.
