You can if you have TeX installed and enable text.usetex in your
configuration. E.g.

In [4]: title('This is $\Gamma$reek to me.')

There isn't much out there that allows a reasonably full range of TeX
without calling out to TeX.

If you want to improve the non-TeX fallback for matplotlib's mathtext
module to support math-mode text embedded in plain text, I'm sure John
would love to see your contribution. It shouldn't be that hard; it's
just nobody's had the motivation to work on it given the availability of
real TeX labels.
