Yes, especially if the reason why we avoid "not negative" aka "0 <="
is because the counter is now unsigned, yours is much more intuitive
way to say "as long as i is not yet zero". Alternatively you could
say "while (i-- != 0 && ...", but not comparing with 0 is more
customary.
Better yet, shouldn't we stay away from "i", if the point of the
change is to make it unsigned, as "i" has a strong connotation with
"int, the platform natural signed integer type"?
