Not quite. A peer may sign his name using only his designation ( eg Sir Torquhil Campbell, Duke of Argyll, signs his name "Argyll" ). A feudal baron, and someone with a territorial desgnation by law must sign his name "MacL of X" so that nobody will mistake them for a peer. Only peers and bishops can sign only their title.
