Technically there's nothing that forbids doing it. It would essentially boil down to port the Python interpreter / VM / Cython (pick your flavour) to run on the naked metal (hard, but not impossible; probably easier done with Lua), which would mostly involve memory management and all the low level stuff to get it running in the first place. Besides all the really hard stuff one had to solve, ironically mapping a pointer-less / array-less language like Python to a page-wise memory model would be rather easy; as soon as one does not have to care about that things like lists and dicts are contiguous in address space suddenly a lot of constraints you'd have in the Linux kernel would vanish.
