Well, that depends.
See, right now OSM's license (CC-by-sa) and point of view is based on
copyright. The upcoming license (ODbL + OFIL) is based on the european
database directive, plus the delief that factual data is, um, facts.
If your point of view is copyright, then the postcode coordinates are
copyrighted by OS (and/or royal mail*); the route would be a derivate product
of OS and OSM data.
* I don't know the specifics of UK
If your point of view is the database directive + facts, then getting the two
individual postcode coordinates is something called "extraction of a
non-substantial part of the data", which is completely allowed. And, the data
you've extracted are facts, and thus not subject to copyright. So, you can do
whatever you want with those coordinates, no strings attached.
You should contact a lawyer, and know OS' point of view about the issue before
doing business with these kind of things.
IMHO, OSM will be a pioneer by assuming this position. I don't know how OS and
other NMAs will respond to the new OSM license and point of view over map
data ownership. There will be interesting times ahead, indeed.

*If* you are assuming that the postcode coordinates are (c) OS, then you
couldn't ""mix"" them with OSM data, and would be infringing either OS'
copyright or a fellow OSM mapper's copyright.
In other words, choose your poison: either infringe OS' copyright, or become
in breach of the CC-by-sa license.
Now, you should weight the risks: Is OS going to sue you for using the
postcode coords internally? Is some OSM mapper or the OSMF going to sue you
for the same reason?
If you assume the database+facts position, then you wouldn't be breaching the
CC-by-sa in any way, but the OS *might* think differently, and sue you.
Cheers,
