I guess it depends on how fitness is defined. I would say a person can definitely have good cardiovascular fitness while being fat. They could also have strong muscles, low blood pressure, low cholesterol, normal glucose levels and generally be healthy. I would describe that as being fit. Seems like weight should be considered one indicator of fitness but not the most important one.
