True that a plane can't take off w/o airflow over the wings to generate lift.
So the underlying question is ... "can a plane generate forward motion (into the wind) on a runway that moves in the opposite direction?"
A car could not, because it generates forward motion by transferring energy to the ground, which would be negated by the conveyor's opposite motion. But a self-propelled plane could still move forward, because it accelerates by pushing the air, irrespective of ground speed or conveyor direction.
