Does the required time to heat a body from 20°C to 40°C the same as from 40°C to 60°C?

Yes, except that the greater the difference in temperature the faster heat moves. So as the hot thing gets hotter it will lose heat to its surroundings faster, which means it will take longer to increase its temperature – and as the hot thing heats up it will be closer in temperature to the thing giving it heat which also means it will take longer.
