In brief: Yes, no, and maybe

Yes, if she knows how to adjust her counting based on the length of her cycles or on which day she usually ovulates.
Yes, if using an ultrasound to do the dating, such as an 8-11 week ultrasound scan. No, if all she uses for counting is the first day of her last menstrual period and her periods are much longer or much shorter than 28 days. And, maybe it matters little, as all dates are estimates.
