It is possible, but not recommended. Lounges at LHR used to be obliged by the airport owner to refuse access to people from other terminals, so you could make it all the way over and find you cannot get in. CX might be more lax.
Getting out of T3 departures is not sign posted, so you need to remember your steps on the way in.
