That happened several times in the British Championship from about 1985 to about 2015.
Nowadays this would be very difficult in a Swiss Tournament with norms on offer, as even minor variations in pairings are not normally allowed.
I would not expect a rescheduling to be allowed (by the arbiter, let alone by FIDE) where the purpose of the request was to increase the norm chances of the player making the request.
I was seeking to make the point that there was no such suspicion in this case.
I'm getting a lot of interesting comments about circumstances where departures from an expected norm of games being played to a fixed schedule might arise but almost nothing about the parameters that must be observed (I say almost because David has given one consideration - 'manipulating norm chances' in the post that crossed with mine). If round 1 can be moved/anticipated, does the final round have to be played by a certain date? I played in several of the e2-e4 APAs albeit not in a norm seeking section. It never occurred to me that if I was unwell I might be permitted to play at another time (not necessarily possible given the two game a day schedule). I believe there may have been at least one event where a game was played out of sequence in the norm section, but the details were not of great significance to me, so haven't been remembered.
