There are a few ways to achieve this on Linux. The Emacs wiki has a some
examples, e.g:

(defun toggle-fullscreen ()
  "Toggle full screen on X11"
  (interactive)
  (when (eq window-system 'x)
    (set-frame-parameter
     nil 'fullscreen
     (when (not (frame-parameter nil 'fullscreen)) 'fullboth))))

Or:
(defun switch-full-screen ()
       (interactive)
       (shell-command "wmctrl -r :ACTIVE: -btoggle,fullscreen"))

The first example also could work with PGTK, but the example only checks for
window system of x build . I'm not sure how exactly fullscreen should be
done on Wayland.

Is the builtin function `toggle-frame-fullscreen` enough?
