No, in this scenario, the MCC will generally give a misleadingly higher value to the larger machine, since it takes into account the higher number of true negatives. In this scenario, this makes it a bad metric.
Obviously, a 100% perfect segmentation would of course register as perfect in both, but in practice one rarely deals with such perfect predictions.
In general, there is no metric that is universally "better" in all scenarios. One is expected to choose the metric that best suits the particular goal one wishes to validate against.
