I believe the answer is 'yes.' A well-designed DAC will add noise with an amplitude of (I think) 1 LSB. So in the first case, the amplitude will be 1/(2^24) and in the second, 1/(2^16).
EDIT After re-reading the question, I'm not so sure. I don't know how a given 24-bit DAC will handle 16-bit data. Would have to look at the spec sheet.
