I'd guess not. It was aging, maintenance was getting ever more expensive, Airbus didn't really want to support it anymore, and it faced ever more competition from better first-class amenities on regular planes, and from the internet reducing the need for fast business travel. It was modestly profitable in its heyday once the capital costs were written off, but it didn't have a lot of headroom. Jet fuel cost about $1/gallon when Concorde retired. Five years later, it would hit $3/gallon. I have to imagine that would have ended it if nothing else had by that point.
