...or can a road have a USRN *and* a UPRN?
Yes. And, in this particular case:
https://taginfo.openstreetmap.org/tags/ref%3AGB%3Auprn=10071171668
(follow the Overpass turbo link to see it mapped)
what we have is what, from a mapping perspective, is a single road
(Glazebury Way), but that comprises multiple OSM ways. So it's not
unreasonable to add the UPRN to all the ways which make up the road.
However, in this case I think I am talking bollocks. Although the OSM
mapper has assigned UPRN 10071171668 to Glazebrook Way, the OS OpenUPRN
OpenUSRN and OpenMap lookups link it to Gairloch Close. If we look at
Gairloch Close (USRN 3230053) on my USRN map:
https://uprn.uk/usrn/3230053
there's a single linked UPRN that appears to be on Glazebury Way, or at
least the intersection of Glazebury Way and Gairloch Close, rather than
one of the properties on Gairloch Close. Follow that link, and it's UPRN
10071171668:
https://uprn.uk/10071171668
Now, there's nothing more we can discover from the maps and lookups,
given that the OS open data doesn't tell us precisely what it is and the
maps aren't sufficiently high-resolution. But if we cheat a bit and go
to the location on Google Maps, then switch into street view:

I have a strong hunch that UPRN 10071171668 is actually a subsurface
property (eg, a utilities conduit) accessed via that manhole cover.
