Yes, a 14-year-old can get a beard.
The development of facial hair, including a beard, is linked to puberty and the influence of male hormones. According to available information, most adolescent boys first notice facial hair between the ages of 13-16 years. This means it's entirely possible for a 14-year-old to start developing a beard, although the thickness and coverage can vary significantly from person to person at this age. Some 14-year-olds might only have a few sparse hairs, while others may have a more noticeable beard.
