Isn't a coach simply a bus with lots of secure luggage space (normally

These days, it would also have seat belts, aircon and quite possibly a
toilet and refreshments. It might also have overhead luggage racks and some
sort of AV system.

BEA / BOAC used double deck coaches mainly for luggage on the lower deck
whilst passengers mainly sat upstairs (diverging I remember when
downstairs a bus was called "inside" as opposed to "outside" for
upstairs)

Yes, those airport buses met my definition of a coach, though of course
they didn't have modern mod-cons.


But public transport coaches are often referred to as single decker
buses.

Those public transport buses are not coaches, however many decks they have.
Most buses are not coaches. It's nothing to do with the number of decks.


In fact see https://en.wikipedia.org/wiki/Single-deck_bus .
Whilst not exclusively British, double deckers are rare in many
countries.

Most single-deck buses are not coaches. But all coaches, whether single or
double-deck, are buses.



Is their an actual definition somewhere or are we just advancing our own
interpretations?


Of course there are definitions. In dictionaries, in legislation and
elsewhere. But this is English so if you don't like the first
definition there'll one another one along shortly
