Welcome to the forum
It is always possible to reduce the neutral if the calculated neutral load is less than the ungrounded conductors. You can actually reduce the neutral, in most cases, as small as the grounding electrode conductor for services or as small as the EGC in a feeder. Most services have many circuits that are phase to phase loads with no neutral so the demand on the neutral is usually less.
With non linear loads it usually is not wise to reduce the neutral.

Where I did was this week for a feeder to a sub-panel.
Where I see it is all over town. Very common to have a reduced neutral.
