I don't believe it is possible with core pagelists.  See these links:

http://pmwiki.org/wiki/PITS/00943
http://www.mail-archive.com/pmwiki-users@pmichaud.com/msg09976.html

(Both are older links, but I'm not aware of any changes to this recently --
there was a more recent discussion of but I couldn't find it in a quick
search.)

Note that with Hans's recent
http://www.pmwiki.org/wiki/Cookbook/FPLTemplateputting together a
recipe for "set intersection" (as requested above) or
"set union" should not be very difficult...
