If there were such a thing, it should probably be a function rather
than a variable.  Doesn't seem there is one, so I wrote it for you:

(defun buffer-narrowed-p ()
  "Return t if buffer is narrowed, nil otherwise."
  (or (> (point-min) 1)
      (< (point-max) (buffer-size))))

The mode-line display is coded in src/xdisp.c, look for "Narrow"
there.

Cheers,
       Sven
