So a lot of older cards with very obscure creature types had their Oracle text changed to make it a more standardized creature type, but still with the original name. For example, see the oracle text of Tombstone Stairwell, which makes a 2/2 Zombie name "Tombspawn," or Wall of Kelp, which makes 0/1 Plant Wall named "Kelp."
One omission, though, is the Homelands card Broken Visage. Not on a lot of people's radars, but I like to use it in Commander because it's a cool card. On the original printed text, it creates a Shadow token. In the Oracle text, this is changed to a Spirit token, but no "named Shadow" like those other cards. Why, I wonder, the discrepancy? There are two printed versions, both referencing the Shadow name (Homelands and 5th Edition), so I don't see why this card is lacking the name while other older token makers keep it.
Note that all of the cards are from core sets 5th edition and older or expansions Tempest Block or older. There are likely other examples but I didn't really feel like going that far into this. I also didn't bother tagging each one with the appropriate version so if you want to see the printed text, you will need to click on them and select the right version.
Looking at this list, they are about even between the ones that keep the name and the ones that don't. A couple of the ones that are given names (Boris, Master of the Hunt, Jungle Patrol, and Stangg) make sense from a flavor or game play standpoint. Tombstone Stairwell kind of makes sense as giving them a name might make them easier to track. It doesn't actually matter based on the text on the card, but maybe the idea was to differentiate those tokens from "normal" Zombie tokens.
