Not according to paul harcourt davies - who is widely acknowledged to be "the man" for macro in the photographic community, he says

Strictly speaking the term "close up" embraces scales of reproduction from 1/20 life size to roughly half life size. True macro photography applies over the range from life size (1:1) to 25x life size , though the upper end is difficult to capture with normal photographic equipment.

incidentally this book (published by David and charles isbn 0 7153 1688-5) is well worth seeking out for anyone with an interest in things macro. its quite pricey at circa 20 quid but you may be able to find a copy at your county library.
