I have a check for $2500.00 written to me. The longhand is written "twenty-five hundred" instead of the standard "two thousand five hundred". Will the banks accept the check?
Nobody cares about what's written there if you deposit it online or on a machine, I tested it once by writing "nothing" in the text field. Even a clerk will probably not even look there.
Only if there are complaints, a human will really look at the check, and humans will understand that term. No issue to be expected.
