Technically no, cannot be stalled in normal law: when speed decreases to Alpha Prot TOGA will be applied (regardless of whether autothrust is engaged) and it becomes increasingly difficult to apply manual nose up pitch. When ALPHA MAX speed is reached it becomes impossible to manually increase pitch beyond the point at which that speed is maintained. If manual input is removed, the aircraft will lower the nose to increase the speed back above ALPHA PROT.
Blocked pitots or similar could lead to an unreliable airspeed situation where the aircraft will react to a perceived overspeed by raising the nose to the point where the stall is approached, normal law will then revert to Alternate law when the discrepancy is picked up, at which point the stall is of course possible.
