If the study comes back revealing that there is a very large population that have been infected asymptomatically, and therefore the fatality rate is an order of magnitude smaller than 1%, would that be a reason to lift some current restrictions?

I can't imagine so.   The immediate goal is still to minimize the (over)load on the healthcare system.  Critical cases are still critical cases even if the figurative bar to be considered a generic case changes.
