Yes:

                         ((and
                           (boundp sym)
                           (documentation-property sym
                                                   'variable-documentation))
                          (help-xref-button 8 'help-variable sym))

seems to work well.  It would still make a hyperlink for the variable
if explicitly preceded by the word "variable", so the author could
still make hyperlinks for undocumented  variables in (I would guess
extremely uncommon) situations where this might actually be desirable.

Sincerely,
