Arguable. Stall warning can trigger in normal law, but I believe the immediate effect will be a law degradation. In normal law the system thinks it is keeping within the envelope, plus a margin, so this is a "should not happen". If it does happen, the system is going to drop envelope protections because it is clear the envelope simply isn't where it was thought to be...
I suspect that it is true to say the by the time you hear the stall warning you are not in normal law...
You have a reference for for this immidiate law degradation effect?
