No. Trademark is for like Pepsico's trademark on Pepsi. This is about image rights, aka rights of publicity. You can satirize, if you do it obviously, the deceased musician Michael Jackson. Likewise some living public person like William Shatner. But you can't use cgi of Michael Jackson or William Shatner to make their "holograms" act in a standard movie for the next 65-odd years without involving MJ's estate.
It's a well-explained subject online for folk that want to do the reading. Some of it is tedious and some I find personally disagreeable.

I'm personally vague on how far satire goes, if you want Jackson or Shatner as side characters or primary characters in porn parodies or biopics.
Separatly, the character "Kirk" is copyrighted, and the name of the character is trademarked.
Copyright and trademark being different legal structures.

> A trademark (also written trade mark or trade-mark) is a form of intellectual property that consists of a word, phrase, symbol, design, or a combination that identifies a product or service from a particular source and distinguishes it from others.[1][2][3] Trademarks can also extend to non-traditional marks like drawings, symbols, 3D shapes like product designs or packaging, sounds, scents, or specific colours used to create a unique identity.[4][5] For example, Pepsi® is a registered trademark associated with soft drinks, and the distinctive shape of the Coca-Cola® bottle is a registered trademark protecting Coca-Cola's packaging design.[6][4]
> The primary function of a trademark is to identify the source of goods or services and prevent consumers from confusing them with those from other sources
