yes, if you export them in the correct fashion. The native blender .blend file format won't work.

Last I looked at poser was with poser 3 for which you could export as .3ds or .obj and then work some magic with poser to turn into native poser items. There was a separate manual wth poser 3 that covered just how to do this, I think you may need to ask some of this in the poser forum where the expertise will be up to date.
