Sure, at least I can. What I do is type the name into the Keyboard Maestro editor search box. Make sure you have clicked on All Macros in the Group Pane first. The results will be all macros that contain actions which refer to that clipboard.
To be fair, the idea that that search box can search for certain kinds of words inside actions isn't entirely obvious. For example you can search for "any" and it will return all the actions which contain the element "while any of the following are true".
