I wouldn't see a problem with using the old toners, the actual toner is just powder so no worries about it drying up like ink. My suggestion is try one in your printer and see how the print quality is, check and more importantly listen for any unusual noises when printing. If the printer makes any weird noises trash the toner since most likely something is stuck inside the toner and it may damage the printer. A check for excess toner in the printer after is a good idea as well.
