The iMac Pro has a TDP of 140 W. The i9-13900K has a TDP of 125 W (although it goes higher on turbo boost). Could I upgrade the iMac Pro to have the 13900k? Is the TDP the only factor that matters when upgrading CPUs?

You prob could but in terms of support and patches, does Apple support that CPU and it might be a case you will run into problems in the future.

How much is that CPU to buy?

It's around $500 to buy. The 14900k also has the same TDP but there's not really a big difference between the two.
As for the software, I can always use Open-core Legacy Patcher if apple stops supporting the iMac Pro, or just use bootcamp and run windows or linux on it.

If I had enough $$, I would actually do this. A 13900K iMac sounds pretty nice. But the price would come to like over $1500 in total.

In short, no. A 13900K isn't going to fit in any Intel Mac model. The 2017 iMac Pro had a Xeon-W with a LGA 2066 socket, and even the last Intel iMac (the 2020 with 10-series chips) had a LGA 1200 socket. The 13900K and 14900K are on LGA 1700.

Aside from the sockets, the chipsets also wouldn't be compatible. Intel typically swaps sockets/chipsets (in terms of compatibility) about every two "real" generations. The 14-series is really a refresh of 13-series (both use Z790 chipsets), and both are compatible with the same LGA 1700 socket with 12-series CPUs and the older Z690 chipset (needs a BIOS update).

Can't you get socket adapters though? I thought I saw those somewhere...
And again, I'm sure you could do some hackintosh-y stuff to make it work.
Edit: looks like you're right. Rip. Anyways, at least you can install faster Xeon chips.

No (those existed a long time ago, but not anytime recently), and the BIOS wouldn't know what to do with it even if it somehow electrically connected (also unlikely because these recent generations use a huge amount of power and need many of those pins for power delivery).

The hackintosh approach would just be building a PC and using software to get macOS to (mostly) run. These days, it's kind of pointless, other than as a hobby project. Apple Silicon is just really good, and my M2 Max Mac Studio feels faster than my 13700K PC in most real work, especially anything that uses a lot of RAM (AS Macs hold up really well under a lot of memory pressure, and PCs noticeably degrade). But, if you're gaming, a separate PC is the way to go. I made it from my 20s to 40s thinking that Macs would be good for gaming any time now. 🤣
