Yes, however you have to make splices in splice boxes, which have to be
accessible. In your case you'd need to find a location where the cable will
reach to, where you can install such a box, or if that won't work, you have
to run a new cable from the switch to the new location




Has anyone ever wondered about the reasons for the boxes required to be
accessible? I certainly agree that it is highly desirable and should
always be done where practical. For example, it makes later trouble
shooting easier.

However, in a case like this, what exactly is the big deal if the box
that contains the splice were not accessible? For example, it doesn;t
suddenly become a fire or safety hazhard, does it? It would seem to me
if you were allowed to use a metal box and cover (to prevent driving a
nail into it) it would still be fine, even if not accessible. And it
would make some jobs a hell of a lot easier.
