I believe that BA and SK don't have an interline agreement anymore, so this means that you'll have to enter Schengen at T2, claim the baggage, and then bring it to the SAS check-in in T5. In my estimate, this would take at least an hour, possibly more. And you need to be back at the airport at least 30 minutes prior to departure, so that leaves perhaps only three hours, or an hour or so in Uppsala. You could see the Uppsala Cathedral, but that's about it. [OT comment removed by mod]
