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.
