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.
No
The other comments mention that it will require the same amount of energy. While that’s true (unless there’s a phase change), the object will lose some of that heat to its surroundings. The hotter it is, the faster it’ll lose heat, so it’ll eventually reach a point where it’s losing as much heat as is being put into it. At that point, it stops heating up.
