A better description would be nouns to verbs -- some na-adjectives are also suru-verbs, but most actual nouns can be verbed with suru (though as in English, some verbing can sound really odd).

(BTW, I still get tripped up by the few-dozen-odd verbs ending -iru/-eru that are actually godan/-u verbs rather than ichidan/-ru verbs. And that's even aside from the deliberately deceptive homonyms like kiru, which as "to wear" is ichidan (kimasu) and as "to cut" is godan (kirimasu).)
