I didn't actually know this before, but after a quick test in my environment I've found that when an invalid icon name is provided, a!richTextIcon() will return a dictionary of data wherein one of the properties is "isError" and a value of "true".

This leads me to think that if you have a strong enough use case for this, you could set up an expression rule i.e. "MYAPP_Util_isValidIconName()" where you pass in the name and it returns TRUE if the result was valid and FALSE otherwise... it seems to execute pretty quickly. Note this would be technically "unsupported" functionality meaning the back-end workings could change in the future with no notice, hence why I recommend only doing this if you have a strong reason for it, and wrapping the functionality in an expression rule and only using that (instead of hardcoding it in).

if(
  property(a!richTextIcon(icon: ri!iconName), "isError", false()),
  false(),
  true()
)
