But with A you don't get in unless you know the password MUST be empty and there MUST be a telnet server on a random port. What's the difference?

The problem is one of probabilities - even the most basic script-kiddie scanners is set up to find your telnet server. Right now there are hundreds, if not thousands, of machines scanning the entire IPv4 space over and over for exactly this kind of silly configuration. If you do something like this it will eventually be found and used.
