I agree 100%. Refurbished can VERY MUCH mean used product and the kicker is that if it's labeled refurb, they don't have to disclose WHY it is labeled such.
Actually, though, on the computer manufacturer websites I checked (Apple, Lenovo, Dell, Sony), they do disclose why it is labeled as refurbished and lay out the criteria. Some make a distinction between "closed box" products and "refurbished" products. For example Lenovo does this. "Closed box" products were returned unopened in their original sealed containers, either because the wrong product was ordered or a company over-ordered and returned a bunch of units. Those would obviously be the safest deal.
From the Lenovo website:
