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

Yes. The amount of energy to go up one degree doesn’t change much on temperature.
There are 2 broad exceptions. If something melts or boils in that temperature range then that’s not going to work. Also the hotter something gets the faster it loses heat to the surrounding environment, so if you lose heat too fast it’s going to be harder to warm something.
