Sure.

I use the following variant:

(defvar rs-tex-texdoc-command "texdoc"
  "Command to display TeX documentation.")

;;;###autoload
(defun rs-tex-texdoc (package)
  "Display TeX documentation for PACKAGE."
  (interactive
   (list (completing-read
          "Display documentation for package: "
          (mapcar 'list
                  (TeX-search-files nil
                                    TeX-file-extensions t t))
          nil nil (thing-at-point 'word))))
  (TeX-run-shell nil (concat rs-tex-texdoc-command " " package) nil))

For the AUCTeX command, it would be nice to use the word at point as
default.  I don't know if my completing list would make sense in
AUCTeX because texdoc doesn't find documentation for all listed
packages.

Bye, Reiner.
