It wouldn't require fewer guests, per se, but since you can consolidate more systems onto a System z box than on an Intel/AMD one, the net effect is a reduction in external networking hardware that is required. Note that, like many high-level arguments, this will not hold true for workloads where a tremendous amount of network traffic needs to be handled. Every case is different, and needs to be examined individually.
