It depends on exactly what you do. If you're slavishly following the
line on the OSM map and collecting a GPS trace of that line, then all
you're really doing is copying (in a somewhat roundabout way) the
coordinates of points along OS's line into OSM, and I think that would
violate OS's copyright. On the other hand if you use the OS map to
determine that there's a Right of Way that needs mapping in a certain
locality, and then collect a GPS trace by following signs and trodden
paths on the ground, that would be fine.
Depending on which part of the country you're in, there might already
be an open dataset of Rights of Way that you can use, which isn't
encumbered by OS's copyright. See the list I maintain at
https://osm.mathmos.net/prow/open-data/ . In theory, Freedom of
Information legislation means any currently-non-available datasets can
be obtained. It can take a bit of effort to do this, but I'm happy to
oblige if someone wants the data opened up for use in OSM.
Best wishes,
Robert.
