Sure, you can do whatever you want. You could even use non-rfc1918 addresses and nobody can stop you. It’s just not always a great idea for your own network’s functionality and security. You can use an unregistered TLD if you want, but it’s worth knowing that when people and companies did that in the past, and the TLD was later registered, things didn’t turn out well for them. You wouldn’t expect .foo to be a TLD, right? And it wasn’t, until it was.
Ah good point. I guess a future-proofed guarantee that the domain will never be used externally would be easier to use than trying to somehow configure my DNS to never update specific addresses.
Certain domain names are locally routed only. So if you use internal or local as a tld, you can just assign whatever names you want and your computer won’t go looking out on the internet for them. This means you and I can both have fileserver.local as an address on our respective network without conflicting. It’s the URI equivalent of 192.168.0.0/16.
Why do I care what ICANN says I can do on my own network? It’s my network, I do what I want.
Try using .com for your internal network and watch the problems arise. Their choice to reserve .internal helps people avoid fqdn collisions.

Well as long as the TLD isn’t used by anyone it should work internally regardless of what ICANN says, especially if I add it to etc/hosts

Interesting that you should use “.local” as an example, as that one’s extra special, aka Multicast DNS
YouCANN do anything you want?
