No, not even slightly. Neither Voyager has much fuel left; in fact, they don't have much fuel even for changing their attitude (the way they point), which is orders of magnitude less fuel than for making major course changes, and the course change necessary to return to Earth is so large it would never have been possible in any case: both probes used gravity assists for the majority of their velocity gain in order to get where they are. The probes would have to have been at least hundreds of times larger than they are to have any chance of returning, meaning we would have to have launched far more into space at one time than has ever been done.
We do know where they're going, though: nowhere in particular. Space is a very very big place.
However, if and when they ever get anywhere with intelligent life, they do have one last possible mission. Both probes have diagrams, long-lasting records, and record playing styluses designed to give possible aliens some idea of what we look like, where the probe came from, and what Earth sounds like. It's very unlikely that this will ever be relevant, but it was considered useful enough to justify the extra few hundred grams. (Also, it gave some fodder to e.g. Star Trek.)
