It's my understanding that hard linked folders will only ever exist inside a time machine backup. Certainly there is no way I can see for a user to create folder hard links* via the finder or terminal. Also, any time machine backup with more than one snapshot in it will almost certainly contain folder hard links. So it seems to me that checking for the existence of a time machine backup is almost exactly equivalent to checking for folder hard links.
Alternatively, If you don't like the idea of checking up front maybe SuperDuper could try to turn journalling on when it hits a hard linked folder instead of just throwing an error.
* Which makes we wonder how SuperDuper does it.
