Re ZM's response, the real answer is, "Technically, no."
As far as I know, not even the most rabid anti-Scot has plans to cut Scotland off and float it off into the North Atlantic. In other words, it will still be just as much a part of Britain as the Rump UK will be after any vote for independence.
In other words, Andy Murray will remain "the last Brit to win Wimbledon Men's Singles ?"
