Chemically yes, physically no. Microwaved water is more buoyant because it has a heat gradient and rarely boils properly. It tends to get superheated and explode rather than boiling.
This is why tea bags float on top of microwaved water but not boiled water.
This. In the microwave, water is heated from top and sides.
In a kettle, it is heated from the bottom. With warm water rising to the top and cold water sinking to the bottom, the water will circulate to evenly distribute heat. This is the main benefit of the kettle.
