No. It’s moving at a constant speed (speed is not changing) in a straight line (same direction so velocity is not changing) so it is not accelerating. Acceleration only occurs if there’s a change in speed/velocity.
In order for the heat to be transferred from the body X to the body Y via conduction, there must be a difference in temperature of body X with respect to body Y. Body X must have a higher temperature than body Y. This process continues until both bodies arrive at thermal equilibrium, meaning they both have the same temperature.
