Yes - try opening the "Window" menu and selecting the Aniamtion Pallette (Busy rendering now, can't check teh exact name). You can select the required frames of the appropriate channels and copy them to paste onto another character. Alternatively you can probably save the pose as an animaiton exclusing morph channels. And so on and so forth... one fo the benefits of Poser is that you can acheive the same ends many different ways (e.g. another way of doing it would be to apply a "young Mike" morph to the animation and save as a new filename. You might have to check that the character doesn't morph back to the old dude due to key frames having been set though).
