No. Plausible deniability depends entirely on what your adversary finds plausible. "I didn't sign that! Look -- I have Thunderbird configured to automatically sign *everything*, and I have no passphrase on my key. Someone got access to my system and sent out a message that got automagically signed by my key!" Such things have happened before. Werner himself has received PGP-signed spam, from some hapless person whose machine had been hijacked and was being used as a botnet to send messages through a PGP signing proxy. Some people will find this explanation plausible. Others will merely find it convenient. Since there is no agreed-upon definition of plausible deniability, GnuPG cannot be said to provide plausible deniability.
