The replacement claim says that HMS Invincible was sunk, Ark Royal was substituted, and another ship was then built in secret. A carrier loss would involve too many sailors, officials, and dockyard workers for the casualties and replacement to remain hidden. A new carrier hull would also occupy one of Britain's limited suitable shipyards, where the construction would be visible to the press and public. The human and industrial footprint of the alleged cover-up is too large to conceal plausibly.

Why the HMS Invincible replacement claim is implausible
The claim that HMS Invincible was lost and secretly substituted during the Falklands War has to account for unhideable casualties, dockyard labour, and a carrier-sized construction project.
