For a minute I thought their name was (without the quotes) "[NAME AVAILABLE ON REQUEST FROM COMPANIES HOUSE]".

Seems like a regulation to add "computer code like expressions" to the list that requires prior approval of the Secretary of State might be useful.

That might require a bit more effort on the part of a company I know, who would have to register their logo "moz://a".

That would be a trade mark rather than a company name in this instance I think. In UK registered trademarks are standard type-written letters for word marks. If they contain symbols then they're figurative marks and it's an image of the mark which is registered.

On that point though, searching on the UK trademark registry it looks like it just strips non-alphanumeric symbols. A search for "Moz://a” returns "moza".
