A company name in Britain has some limitations, on words like Royal, England, Council, Chartered. But I don't see any restrictions with place names, except the country names.
In UK and EU law, it's the opposite: Geographical names are expressly excluded from TM rights, unless there's significant reason that they should be protected. Even then, it's only protected to the extent that its use causes trade confusion.
