It's possible, yes. But it's not really usable. I tried Linux on the STM32F469 discovery board and the only takeaway was "Cool, it works". Feels more like a proof of concept than anything you'd want to use in a product. It's slow and everything takes forever, barely any of the interfaces work and basically all of your resources are gone just to run Linux itself.

  Cortex-M4 doesn’t have virtual memory, the only Linux you could run there would be a ucLinux fork

The key difference is that F4, F7, and embedded chips in general don't have an MMU. This is a strong requirement for "regular" Linux (and other desktop OS's).
