Is it possible to distinguish information encoded with a single pass from random noise?

Question

I understand that cyphertext from a correctly used single pause timer contains absolutely no data about the encrypted message.

Does this mean that it is impossible to distinguish a message encrypted with a one-time pad from completely random noise? Or is there some theoretical way to determine that there is a message, although you will not know anything about it?
