No, "stall" refers to a completely disturbed airflow state over an airfoil and as such an alpha that's past alpha max, and not to the effect of a device that would prevent the aerodynamics phenomenon to happen.
Hmmm...... not according to the regulation by which all modern aircraft are certified.
I know exactly what you mean by the classic definition but we now have FBW systems which prevent it happening. Even before FBW if an aeroplane had stall characteristics which were no deemed appropriate a stick pusher was used to prevent the aircraft from reaching the classical "stall".
