Perhaps in a very narrow sense, but I think it's more complicated than that. Let's assume that there are facts that a person has a legitimate right to conceal in a particular context. What if the only way to conceal such a fact is to create a false impression? I would hesitate to call that lying, because the word lying ususally implies that it is not legitimate, which contradicts the assumption.
