As lyx is not listed in 'Writing R Extensions', the one (authorative) manual describing how to build packages for R, I would not assume it to be present on every CRAN machine building packages. Also note that several user recently had to ask here how to deal with less common fonts for style files for (pdf)latex.
So I would recommend 'localising' the pdf creation to your own machine, and to ship the resulting pdf. You can have pre-made pdfs as core of a vignette, I trick I quite like to make package building simpler and more robust. See https://www.r-bloggers.com/2019/01/add-a-static-pdf-vignette-to-an-r-package/ for details.
