However, if I pull nose up at 50 kts with full flaps, stall will be imminent, without even being able to reach 20 degrees pitch up.
I am not disagreeing with what you say, just interested in the answer. In ground school we learned about the critical angle and that a stall can happen at any speed etc etc, but then we learn about Vs, Vs1 etc and see our susceptibility to stall is determined according to these speeds, even with 0 degrees pitch you'll stall at not much beneath them.
A stall at Va is a limit load. Any stall above Va is an ultimate load
