Why wouldn't it be able to? Strip back linux and it can run on almost anything. Its been running on PC's since those specs were normal for a desktop lol. The original Pentiums went as low as 60MHz and they could still run just fine. EDIT: Looks like its not, but I still dont see why it couldn't. May not be very useful though.

  Typically a lack of MMU is the blocker for microcontrollers. Although constraints on RAM and storage can also make it inpractical.

It isn't. It runs InfiniTime.
