Indeed it is. Obesity is a strong risk factor for OSA. One less-than-obvious place obese individuals store fat is in the soft tissue of the pharynx. This narrows the pharynx, and when they fall asleep (and hence lose pharyngeal muscle tone) their pharynx closes (ie, the sides touch), cutting off their airstream. In contrast, it’s not at all clear (to me) how well-developed traps, scalene muscles, SCMs, etc, could cause a similar collapse of the pharynx.
I would say neck size in BBers/weightlifters as a risk factor for OSA is misleading in the same sense that BMI is a misleading indicator of body composition in BBers.
All that said, it should be noted that certain aspects of weightlifting can put an individual at risk for OSA. For example, a ‘full house’ weightlifter may be carrying significant amounts of BF, some of which may be stored in their pharynx. Further, we know that TRT seems to exacerbate OSA, so it stands to reason that excessively high T levels in a younger individual (ie, juicing) might do the same.
