Hi
I have a Laguna 14 SE so older than yours.
I use a 3/4” resaw blade with no problem. I think it’s a wood slicer from Highland. Bought it years ago.
As an aside, Not sure if they still say this, but Laguna claimed my saw could handle a 1” blade. I tried and It sort of fit but not really well.

It's not hard to figure out whether or not your saw can handle a 3/4" blade. Make a tension meter and check the tension on the blades you have now. Here's a link to my web page that describes building and using a
tension meter.
Let's say you find you can easily apply 20K psi on the 1/2" blades you now use, and the tension meter is someplace close to the 1/2" tension indicator on the saw. That would suggest that the saw probably can apply at least 20K psi on a 3/4" blade. 25 K psi would be better on a carbide tipped blade like the Resaw King, FWIW. The good news is the Resaw King uses a narrow gage band so applying higher tension requires less spring force than on something like a Lennox carbide blade. However, if you find that in order to get even just 20K psi on your 1/2" blade that the tension indicator is at or almost at the 3/4" tension indicator then it's pretty clear it can't handle a 3/4" blade.
It's better to run a 1/2" blade at 20K psi than a 3/4" blade at (20/0.75x0.5)= 13K psi.

I've not noticed any decrease in what I can do or the quality of the result in moving from a 3/4" RK to a 1/2" RK. YMMV of course based on what you do.
When I was young I sought the wisdom of the ages. Now it seems I've found the wiz-dumb of the age-ed.

I'd be very surprised if the 1412 will tension a 3/4" carbide blade properly.
Even if the spring will produce the force, I seriously doubt the the spine could handle it without flexing.
I can't really see an advantage (or better results) by you switching to 3/4" ; but I can see exposure to poorer results. Just like GeeDub's experience.

"A narrower blade has lower beam strength so the maximum rate of cut is lower even for blades with the same tooth count."
I would think a thinner blade regardless of width, would cut faster than a thicker one.
