Not simply, if you purchase anything from a dealer or the Avid store that will get you up to the latest stuff, depending on how you exactly did that you could also run Pro Tools 12.. but why would you when you could also run Pro Tools 2020.5 with that license bundle.
You could purchase a used Pro Tools 12.6 or later licenses (be careful it's not a 12.5 or earlier license). And do a formal license transfer and all the other dicking around. And risk being ripped off, and maybe not saving anything anyhow even if you were not ripped off. Personally I'd not bother.
Your choices to get to 2020.5 are to switch to a subscription plan, you can do that with any dealer or on Avid's online store. Or to purchase a license reinstatement which you can only do from dealers (like this

If you are not sure of your options, don't understand subscription vs perpetual with annual update/support fees etc. then I would phone Sweetwater and talk to a sales rep.
