No. It's impossible, as the writers usually pull the stardates out of their ass. If we assume the TNG and TOS systems are the same system, though, it would seem to be a logarimthmic function, approximatly increasing by a factor 10 every century. That would mean ENT would take place around stardate 350, and we would now be somewhere around stardate 10.
The Trek XI stardates, however, are probably possible (and not even that hard), as these actually make sense.
