I don't see why you couldn't since it is no different than connecting the negatives to their respective battery's negative post. They are all electrically connected after all. My Xantrex 2 bank charger only has a single negative wire, and then a positive for each bank.
Of course the prudent thing to do is to read the manual for your specific charger!
