Boeing has long designed their stabilizers to have a huge stall margin with 3 inch ice shapes, which is how they can certificate without ice protection. To my knowledge, there are no tailplane stall events in any legacy Boeing airplane...the MD80/DC-9 does have a history of tailplane stall behaviors with flaps 40 in icjng (hence the QRH procedure for a flaps 28 landing if the ice protection has failed).
Tailplane stall nearly always requires full flap extension. MCAS is not operative with flaps extended.
