I believe the answer is no, but see here:

So from there the answer is yes :P. As long as you use FastPWM instead of regular pwm.

Looks like if I use Eric Olieman's fastPWM libraries I can hit higher than 0.5MHz. Not sure how high it can hit on the STM32F401RE because I don't have an oscilloscope to check it out yet.
