It would depends on the fiction we're talking about.

In a setting where the mind is a function of the brain and the user turns into an mass of their element with no part being more important than, they would be immune as they would no longer have a brain. But in a setting where body and mind are two separate things, they would not be immune to Telepathy as passing through the body (the brain) would not be necessary to access their mind.
