No. That is what is meant when the Doctor refers to the war as "Time Locked". The Time Lords (and the Daleks) are trapped in that war and do not exist anywhere or anytime outside of it. Occasionally the Doctor has encounted past versions of himself, notably in "Time Crash" when the Tenth Doctor met the Fifth Doctor. The mechanism by which the Doctor avoid himself isn't explained. It's most likely that he simply doesn't travel to the same locations. As seen in "The Doctor's Wife", the TARDIS has claimed responsibility for always taking the Doctor "where [he] needed to go", so it's entirely possible that the TARDIS prevents the Doctor from landing where he has been before. It's also possible that the Doctor remembers where he has been and doesn't go again.
