Short answer: no. "Windows mobile" and "Windows XP/Vista" are
completely different code bases. Marketing is what links them. It is a
similar situation to Windows XP vs ubuntu: apps have to have different
calls to interact with the OS.
There might be x86 emulators for Windows mobile but I doubt they'd
have the performance to run ubuntu as they will have to do full CPU
emulation, which is going to be very slow on an embedded CPU*. It
might be possible to build a virtualisation app that would let you run
ubuntu compiled for the CPU architecture in the device with reasonable
performance but that is likely to be a big undertaking.

* Don't read clock rates for embedded processors and think performance
will be comparable to a desktop processor with that clock
rate. Embedded chips tend to use simpler instructions so you get a
smaller chunk of work for each clock tick, they have simpler branch
prediction so are wrong more often, and tend to have less
parallelism in the hardware to save power. The lower performance is
to let the battery last more than the few minutes it could power a
desktop CPU.
