I don't think so, but we can try to create it.

(defcustom apropos-whole-words t
  "Whether the apropos commands should search for whole words."
  :group 'apropos
  :type 'boolean)

(defadvice apropos-parse-pattern (before rewrite-pattern-ad activate)
  (when (and apropos-whole-words
             (consp (ad-get-arg 0)))
    (ad-set-arg 0 (mapcar (lambda (p)
                            (format "\\<%s\\>" p))
                          (ad-get-arg 0)))))
