Yep. I too can attest to Wine working just fine in Mageia 4.
Installed Wine the other day, and so far have installed the 5 applications I wished to use under it (these are ones from Win Xp that I happen to have had NO luck finding an equal or better to).
All 5 work like champs. In actuality, 4 of them are actually QUICKER under Wine than under XP. Go figure.
The 5th, it is basically the same speed, or if "slightly" quicker cannot differentiate with human eyes.
