Perhaps this approach works: you define an alist which you then use
for completion.  The keys of the alist are names, the values are
strings to pass to telnet.

(defvar tennis-routers
        '(("one" "10.10.10.1" 42)))

(defun tennis-telnet (router)
  (interactive
    (list (completing-read "Router: " tennis-routers)))
  ;; At this point, router is a string.  We make it the complete
  ;; entry in tennis-routers.
  (setq router (assoc router tennis-routers))
  (telnet (nth 1 router) (nth 2 router))
  (rename-buffer (nth 0 router)))

I haven't tested it.
