Absolutely not. Well not in OSM terms anyway. To the Highways Agency a Trunk Road is a road they maintain. These days that is basically as few as they can get away with and at the slightest whiff of an opportunity they will detrunk it and hand it back to the local council to deal with. To OSM a highway=trunk is any road which is part of the Primary Route Network. That is so say all green signed A roads. That will generally include all current (and former) centrally maintained Trunk Roads as well as some roads which were probably never centrally maintained. We did get a complete list of the Primary Route Network from DfT a few years back.
