--------- I am trying unsuccessfully to have COFFEE undo the creation of a base tag in R10.x.
Undo calls work perfectly in the following example in R9.6 but have no effect in R10.x. (This code goes into a COFFEE expression tag with a Boole user data element to trigger creation of a display tag.)

Can anyone tell me why this is not working in R10.x?

To be honest this loks like a hack. You shouldn't create nodes (object/tags/materials, etc.) from within an expression. An expression plugin with an interface where you can catch a button message is probably a better idea because this happens outside of the expression.
cheers, Matthias

Thanks for the guidance, Matthias. Looks like I'll have to create an interface for the plugin. Björn mentioned this on the CGTalk forum a couple of years ago too but I had forgotten.
