take your point but I also think it's true that in the case of these language schools the owners are implying a connection.Your Kew Landscapes is simply using the location, as that's where the company was based. A bit like Blackpool Lighting company, based in Blackpool.
As for 'Oak Lane' it could be that there is a historical connection. Much of England was heavily forested in medieval times. There are other examples in London where the street name may puzzle visitors but have an historical context.
Fair enough there's a lot in what you say.
Dickens is good for getting a grip with London, how it was, and how some of the same streets we have today, how they were then. In particular his account of The Riots and storming of Newgate et cetera. In face you can learn a lot of how things were all over the country, don't you think, from reading his novels?
