The CW has all sorts of rights, they have the rights to any character, Warner Bros/DC just gives the TV shows some rules to follow (no Joker, No Superman/Batman sometimes), I believe one of the rules was no Deathstroke after Justice League came out but realizing that these are more successful those rules have been relaxed.
