Eric Abrahamsen:
the `org-map-entries' function can be given a scope of 'agenda

That worked perfectly, thanks. Here's what I ended up with:

(org-map-entries (lambda ()
                           (when (equal title (org-get-heading t t))
                             (org-entry-put (point) "TODO" "DONE")))
                         tag 'agenda)

Depending on how automated you need this to be, the `org-map-entries'
function can be given a scope of 'agenda (see its docstring). You could
call it with the agenda scope and a matcher for the "laptop" tag -- that
would at least get you all the headings in all the agenda files with the
"laptop" tag. Then the actual mapping function could call
`org-get-heading' on each of the matching headings, and check the text.

In these cases, though, I generally try to find a way to know the
heading's ID property, and use `org-id-goto'.

Hope that helps,
