This is absolutely the case, the route inside the M25 is almost entirely tunnelled, there is a 10 mile tunnel through the Chilterns, but if Liverpool wants a captive HS2 station, which would require 2-3 miles of tunnel, or Manchester wants a through station and NPR tunnel out to the east that costs too much. In London and the South East no cost was spared, in the North people are expected to get by with reused existing lines and an urban viaduct.
Without wanting to get too far off-topic, I don't believe that is entirely correct. In London, the idea of a direct HS1-HS2 connection was never progressed, in part because of cost. And more recently, IIRC the HS2 Euston station plan has lost a platform precisely in order to cut costs. So cost-cutting has been done in London.
The tunnelling in London is largely because there is no alternative. In Manchester there is an alternative to the underground station. I'm pretty sure that, if there happened to be a suitable disused station next to Euston that could reasonably have been repurposed for HS2, thereby saving £many billions, then that would have been done - but there isn't. In Manchester, there is, so it's hardly unreasonable of the Government to seek to use it!
