Depends on the stall being due to a lack of airspeed or the aircraft exceeding the critical angle of angle and it still has airspeed.
The ASI reads through a line roughly parallel to the angle of incidence so if it still has airspeed in that direction it isn't stalled. If the AOA is exceeded the airspeed has bugger all to do with it. I think!
Jock will now kick my arse no doubt.
