To clarify, in light of the comment by sdenham: "I feel that adding ‘alleged’ to the question makes it almost meaningless (the answer is, trivially, ‘no’.) If it is merely alleged that a person has committed a murder, we cannot conclude they have killed someone." the question is saying that it has been alleged that qualia don't exist, and asking whether, if the allegation is correct, that would imply that it is meaningless to say that what I call "red" could be what you call "blue".
