Yes!! Office 2010 and Office 2007 integrate with both MOSS2007 and SP2010. Of course the Office 2010 client and SharePoint 2010 server each add functionalities...
I'm pretty sure Microsoft has posted an updated guide to Office/SharePoint integration (an update to their "good better best" white paper in MOSS2007)... can't find it right now but I'm very confident I've seen it before.
