the plane can take off by running its engines as if it was taking off from the stationary runway. The engine thrust would move the plane forward on the conveyor belt at a normal relative velocity to the still air over the conveyor, the wheels will just spin much faster to accommodate the backward motion of the conveyor.
When a plane is accelerating down the runway to take off, the air resistance of the wings, fuselage abs empennage vastly exceed the rolling resistance of the landing gear, almost all of the engine thrust is devoted to overcoming air drag and accelerating the mass of the plane against inertia. The fact that the wheels are creating more rolling resistance when rolling twice as fast as normal will have little material impact on the plane’s ability to achieve take off speed relative to still air.
The effort will, however, probably overheat and destroy the tires and bearings of the landing gear wheels that’s not been designed to roll twice as fast as normal take off speed while under the load of the aircraft’s weight
so i guess whether or not the plane can take off depends on whether the landing gear will be damaged enough by rolling twice as fast as intended to actually seize up, causing it to be ripped off and the plane collapse onto its belly before it can actually take off.
