No.  C-u delivers a non-numeric value (a list, actually) for the
corresponding arg if "P" is used in the interactive spec.  If "N" or
"p" is specified, it is automatically converted to a number (a power
of 4 depending on how many times C-u was pressed).

C-h f interactive RET


(defun show-me-C-u (arg)
  (interactive "P")
  (message "ARG is %s." arg))
