Probably no change to the chain.
The chain length would be dependent on the position of the hub in the dropout. With some fudge factor with the rear derailleur. Also dependent on chainring and rear sprocket sizes.
Simply changing the wheel size, assuming it fits, shouldn't impact the chain.
One general rule, never use a well used chain with a new rear cassette/freewheel.
