No, not unless you know that the port's implementation is sufficiently constrained. In general, reading from a port can involve thread switches and synchronization, and those are not allowed in callbacks from foreign libraries. (BC doesn't prohibit non-atomic callbacks as aggressively as CS, but interacting with the Racket thread scheduler from a callback can go wrong in various ways with BC, too.)
