I'm afraid probably they have not.

A recent tendency in 'animé-isation' of 4-koma manga is that 4-koma manga which are chosen are mainly so-called moé 4-koma. So, in view of it, now the chances may not be very high that a non-moé 4-koma will be made into an anime.
In a 'Which 4-koma manga do you want to see as an anime?' thread of 2ch, people often mentioned also non-moé 4-koma, non-otacky 4 koma, 'family' 4-koma, 'fundamentalist' 4-koma, 'old school' 4-koma, and the like, though. (OL Shinkaron and Kashimashi House, too, were mentioned.)
　

To give more details about this:

(There was also a jinx on Kirara 4-koma manga: a Kirara 4-koma manga which had a drama CD cannot have its anime version. But the jinx was broken with Acchi Kocchi's having its anime version.)

Except some very popular/prestigious titles, basically, media franchise-wise, 4-koma manga have been not big, in comparison with standard-format manga. So, many 4-koma manga didn't/couldn't cross over from their original medium to other forms, especially to anime.
Even if a 4-koma manga has its CD drama, usually it is something like an 'I want a motorcar, but I cannot afford a limousine and a chauffeur, so I buy a minicar' thing.
Another factor which can be taken into account is a matter of the sub-genre 'moé 4-koma'. So-called moé 4-koma are recent 4-koma manga which have otacky styles and contents and are aimed at younger otacky readers. As a matter of course, moé 4-koma have more chances to cross over from their original medium to other forms than non-moé 4-koma. But non-Kirara Hōbunsha 4-koma manga are non-moé 4-koma, non-otacky 4 koma, 'family' 4-koma, 'fundamentalist' 4-koma, 'old school' 4-koma, and the like. So, non-Kirara Hōbunsha 4-koma manga have less chances, and people tend to think that to have a drama CD is probably the limit of a non-moé 4-koma's capacity, even if it is so-so popular. Therefore, people also tend to think that there is such a jinx as that.

In fact, Dr Akira, Radical Hospital, Love Lab and Honey Café are non-Kirara Hōbunsha 4-koma manga and have drama CDs, but they don't/cannot cross over from their original medium to anime.

Hōbunsha also publishes 4-koma magazines which carry non-moé 4-koma manga.
