No. It's a special arrangement between Google and WhatsApp which makes a file only visible to WhatsApp, and not appear in your regular drive so you can't do normal cloud file operations like generating public links.

Without evidence of this “special arrangement” I don’t see why anyone should believe you. You made a claim that is directly contrary to WhatsApp’s published materials and they have a lot to lose if you are correct. On the other hand, if your accusation is false, it’s tantamount to libel.
