It Depends
No animal products are found in Oreo's ingredients, so in that sense they are vegan.
It is important to note, however, that Nabisco's (the producer of Oreos) production lines are not separated, so it is possible for Oreos to contain trace amounts of milk.
Furthermore, Oreos contain palm oil. Many vegans choose to avoid palm oil because of its destructive means of production, with concerns ranging from habit destruction and deforestation to species extinction and human rights violations.

The main difference between category 'A' and category 'B' is the harmful qualities typically present in 'B' items. Serious side effects are usually uncommon, but are still possible and should be taken note of.
