Indeed, the original CAZ was much larger (and indeed went further into Gateshead). Effectively the 'border' is now any of the bridges:

So to answer the original question - yes, if an operator was inclined to do so, they could terminate a service at Gateshead rather than run it into Newcastle, to avoid a £50 charge if the vehicle is non-compliant. It wouldn't really be in the operator's interests to do this as the majority of its passengers are in Newcastle, but there are a fair few peak-time journeys which run on/off scholars or other services which don't usually operate into Newcastle, so either these will need to be upgraded to Euro 6, or they won't run as they do currently.
