A 16 gb optane m.2 drive will work in a pcie x4 m.2 slot right?

Yes, but it is pretty useless. Can't you find anything bigger?

I  don’t need it to be bigger, it’s a boot drive for truenas scale only

Really making the cpu work to boot as fast as possible

It's not just about speed, these little Optane drives go for SD card prices and they have extremely high endurance. Even the tiny 32 gig Optane M10 is rated for 365 TBW.

High endurance for their size I guess. The 16 gb are less than half of that and really aren't that fast. (250MB/s write, 900 MB/s read)

That's still more than a 256 gig Crucial P5 Plus is rated for, and that's a drive with 16 times the capacity.

 

I've been rebuilding my "production" home server again, and I've got a 32 gig M10 as the new boot drive. (I originally intended to use the internal dual SD module, but even cards designed for dash cams and security cameras don't last very long under a modern OS load. Those are really only meant to hold static boot images for OSes that run entirely in RAM.)

The perceived uselessness of those 16GB optane, makes them very inexpensive.

SSD prices are going up  anyway it seems.

 

 

This in turn makes them useful again - for some things. Mainly it is the  due  to the random Q1T1  random 4k reads of  about 160MB/s.

It is better than nearly all standard NAND drives.

They have  various uses in a home server, especially truenas.

Also great as boot drives for linux & linux based servers also.

They can also be used as a cache, which was their intention.

 

The endurance is good for the size, but who cares. Just use them in pairs if need be & replace a failure.
