Definitely not at this time (if you mean in the simulator).
It has also not been announced nor, as far as I recall, even yet mentioned as a possibility by RIM staff.
I have seen one stray comment (probably not official) about an Android emulation layer being a possibility, and if that's the case then surely a BlackBerry layer would be as well, but absolutely do not count on it at this point.
And if you are asking merely about whether there's any source compatibility by providing identical APIs, I can't really answer that. BlackBerrys don't use AIR, of course, so you'd presumably need to wait and see whether the Java APIs for PlayBook are designed to be compatible in any way. I'm going to guess they will not be, at least in the first version (which has neither been released, nor even promised for any particular date, though it could come out tomorrow for all I would know).
