You can either save as or export for screens. The latter creates the more modern code.
You can then use the W3C validator to validate the SVG code.
That is all you can do from your side.
But that doesn't guarantee that the cutting machine can work with the code. The software might be expecting something very specific (specific line weights, specific colors, specific layers names, whatever). The software might also reject your SVG although it is valid.
You just can't know.
The only thing you can do is have some test clients who cut the files on different machines and give feedback. And this is what people do when they offer cut files for sale.
