Try comparing the basic instruction lists at the start of the assembly instructions from the data book for the 16C5X and the 16CXX parts and you will find very little difference. The 'CXX parts have 2 extra instuctions. - RETFIE and RETURN. The 17cXX devices are different as they have 55 instructions, but most of the 16CXX instructions are implemented.
