I would also find out who has zoning authority and ask them if
there might be any trouble for your neighbor. Sometimes zoning rules
require minimum lot sizes.

And even if the lot size will be fine, don't they often require a
minimum distance between the house and the lot boundary? Moving the
boundary 10 feet could put it to close to the house.

Good point. Might also run into easement problems putting a fence up
across the "new" area.
