Im feeling  on a lot of things but for just consistencys sake I vote for Chinese yuan Its unlikely if not inconceivable that someone would link to Chinese yuan if they meant the dynasty and as soon as you start reading the article you gonna know what its about PS It also appears that the phrase Chinese yuan is not unheardof if only for  aha  consistency and to make it clear what countrys currency it is On the flipside though I will say whatre the odds someonell link to Yuan when they meant to link to Yuan dynasty
