Mobile network T&Cs, oversubscription, and asymmetric connections prevent hosting on mobile devices more than any limitations of the OS. Mobile devices themselves also don't make great web servers because their scheduling and power management is tuned for battery life and not responsiveness to a random distribution of incoming network requests. Even if you had some fully unlocked Linux system on a phone it would still make a crappy web server. You'd be a lot better off with a Raspberry Pi with an LTE modem but you'd quickly run into problems on the mobile network side.
