May I suggest a slightly different formulation of this idea which has a
bit of tidying-up?

  menuentry "Disclaimer:" {
	configfile /boot/grub/menu.cfg
  }

  menuentry "Do not use this computer" {
        configfile /boot/grub/menu.cfg
  }

  menuentry "  unless authorised  " {
        configfile /boot/grub/menu.cfg
  }

menu.cfg would contain

  menuentry "Linux" {
	linux   /vmlinuz
	initrd  /initrd.img
 }
  menuentry "Windows" {
	chainloader ...
  }

Either way, the OP would have to consider how to handle update-grub.
