Yes and no. One of the things about working at/near stalling speeds is that dropping an airleron to pick up your wing can add just enough drag that the outboard wing panel stalls too.
Normal procedure in that part of the flight envelope is to pick up the dropping wing with rudder. IOW, leave the ailerons alone even though they "technically" will still work.

Not exactly true. When you are on the edge of a stall, using aileron to pick up a wing makes the wing work harder (ie. produces more lift). This means that the wing you are trying to pick up will actually stall as it is working harder. That wing will then drop, rather than pick up. This is called "aileron reversal".
(A friend of mine was in the back seat of a Cherokee when a student pilot caused aileron reversal while on short final. This managed to get the instructor to scream...
