In brief: Could be, but

It is likely that atherosclerosis would be present both in anterior and posterior circulations to some extent, but there could be more obstruction in vertebral-basilar system than in carotid areas.
The syndome called "tip of the basilar" is such an isolated issue. A fully blocked basilar artery could be a seriously malignant stroke and could contribute to rapid demise.
