Yes, enamel used to mean only thinner-based but no more. In fact, even the term alkyd is no longer only thinner-based. (both now used in the acrylic world as well) I'm a professional painter and I'm continually caught wondering what's compatible these days. I can safely say that when I use thinner based 'sanding sealer" on new wood - I can use it both as a sealer and as a leveler (for eliminating grain) without fear. Many coats, sanding between coats - final product an excellent base for what's next. Here in CA, it gets harder every day to buy the tried and true products I've counted on. Not complaining in terms of reducing toxins - but for example, "Simple Green" has never impressed me compared to "409" as an effective grease-cutting cleaner. And don't get me started about the pathetic version of "paint stripper" we have to use here.
So in general, as long as the finish product does not attack the under-coat product, you're good. For the record, enamel is soft and will never really get as hard and durable as the poly-resins used commercially today. Lacquer is more demanding to work with (specific cure time once done spraying) but can offer much more flexibility as far as layering/buffing etc. My advice (up to you to accept it or not) is: keep it thin, keep it clean & smooth through the process, make sure the temps are moderate, the humidity and wind low (if spraying outsides) and keep your spraying ventilated.
