You can't, it's there for 'eternity'...think about any games played under its guise, those challenges will always remain as a resource. If you could delete one half of a game, then that game didn't actually take place.
EDIT: All you can do it is try, like the many before you, to offload the clan...try inviting someone to take it over, go to 'clans' forum and ask. That's the only way you can rid it from your profile.
