No, by UEFA rules we can only have 4 teams in the CL. So if Madrid, Barca, or Valencia win the CL but don't finish in the top 4 in Spain, well tough luck to the 4th place team, they will be in the UEFA Cup. No league can have more than 4 representatives in the CL.

Well Italy had a similar (well not 3 teams in the semi's) situation. Juve could've won the CL but they were well down in their own league. Anyhow, what UEFA said was that if Juve won the CL, Italy would still send only 4 representatives. So the 4th place team in that case was out of luck. By the way, that situation when Real Madrid won the CL and then Spain sent 3 teams to the CL next season was before the current format (same thing happend to the Bundesliga the year before). So those were slightly different rules than this season.
