No. My Yorkshire pudding pan has four very shallow indentations which I imagine is a bit different from a popover pan, I think.
Genuine Yorkshire pudding should be cooked directly under the beef in a very big pan. As far as I can see, there is no difference between a popover and Yorkshire pudding except for the beef drippings. It is the same recipe as pancakes. And so delicious!
Yorkshire Pudding and Popovers always taste much better to me than Pancakes ;-)
