Can a whole rest be used in 6/8 time?

A semibreve rest CAN be used in 6/8 time - or ANY time (apart from 4/2 - quite unusual)) to represent one bar's rest. At that point, it isn't actually a 'semibreve', but represents just one bar of that music. It's become a shorthand way of saying "one whole bar rest".
