4:20 would be converted to 420 (four hundred twenty) so that would be CDXX. However to make it easier for one to read, I'd leave it as 2 separate numbers 4 and 20, or IV and XX aka IV:XX.
But normally, we don't use roman numerals for time in that way. A clock will only say the hour in roman numerals, but not the minutes.
