Simple answer - no.

Anything less than 24 hours is considered a connection and is not charged for. Any more than 24 hours is a stopover, and ups the price.

If you were on United it might be possible to use same-day change to move to a later flight within 24 hours of the flight (although there would be a fee), but Lufthansa don't have anything similar - and it's the airline that you're flying that matters.
