recap vs recap is definitely a distinction that shows up in my western canadian speech patterns. Absent is a pretty subtle difference.

I suspect a lot of these vary with regional accents.

The stress difference on cushion is there, but it's very faint. Absent and recap aren't really ever used as direct verbs that I've heard.

E.g. "I am going to be absent" and "I am going to recap you on this" (or really the more natural "I'll give you a recap" where it is not used as a verb at all) is the most common form I hear in the US

I was going to comment the same thing. While many on the list follow the rule many other words listed I've heard only one pronunciation regardless noun and verb form. Maybe it's a regional thing. I speak American English, maybe these pronunciations are different elsewhere.

I've certainly heard "abSENT" in British English. The other two, not so much.

I absent myself from this discussion

Odd, I speak bog-standard American English and if I abSENT myself from class I will be marked ABsent.

Though I would CUSHion a blow with a CUSHion, I would also say "to reCAP, I was just telling Bob that you missed the REcap".

Not for cushion, but I've heard the other two.

Invalid though two distinct nouns and not noun verb, isn’t listed here. I know there are others, just don’t recall at the moment.

"Cushion" is a particularly bizarre example, because even if speakers were to stress the second syllable when using it as a verb, it still wouldn't demonstrate initial-stress derivation. The noun "cushion" is not derived from the verb "cushion." It's the other way round. (Source: the Oxford English Dictionary, unfortunately behind a paywall.)
