You'd have to be over 30min late for the connection to be at risk, something rarely happening on long haul.

LX does have a very good system at making the connections, even if you're a bit late. They often hold long haul departures with connecting pax for a reasonable amount of time.

There is nothing to worry for you about. If your flight is on time, you'll have enough time for the lounge even.
