Not exactly.
The biggest difference between the two is that the URL->URL version is
guaranteed to make a copy of .../trunk at the HEAD revision to
.../tags/FOO. If, however, you do this operation WC->WC, you add a
LOT of complexity. Namely, if you .../trunk is not up-to-date, or
otherwise contains mixed revisions (as in, /trunk is at revision 2,
/trunk/A is at at revision 4, /trunk/B is at revision 5, etc...) then
you are actually copying those individual revisions of everything to
the new location.
Secondly (and this is minor), doing the WC->WC copy + a commit will
actually add an entry for FOO in your .../tags/.svn/entries. Of
course, you rm'd the FOO directory, so status should show it as
versioned but missing from disk. URL->URL copy will not make any
changes to your working copy.
