if its R12 no you cant. if its been updated to an R134 A/C system, you should be good to go.

If it has been updated by a reputable shop, big word for me, there will be a sticker on the fan shroud, or the frion resevoir will have one. If theres nothing saying "R134." chances are its not. Any shop that does A/C work can update it, I'm not sure of cost though.
