Not right now, and it would be a nontrivial task to make it work. Android doesn't have all the libraries that the typical desktop JRE does. Although since Android is open source and it will run anything that can be compiled to Dalvik byte code, it's not impossible.
Really, I don't really think JavaFX will make for more attractive looking Android applications - the most important thing is how integrated the application is into the hardware and the Android display framework has a lot of stuff to make that easier.
