Can the telephone drop wire (the wire that comes into my house from
outside) be temporarily disconnected, without causing anything
undesirable to happen to the telephone system?

The wire comes into my house and terminates at a junction box, where
only the orange and white are connected. A very short length of wire
leaves this junction box to be terminated at a master socket.

I want to re-route the path that the drop wire takes as it comes into my
house, and this requires disconnecting it so it can be threaded through
a different path.

No problems but make sure to connect it back correctly and insulate
against possible shorts or indeed touching a conductor while moving it.
Although the DC voltage is nominally safe, the ringing volts could give
you a nasty surprise. So treat it as you would a live mains cable.
