It's OK. On a boy, because
Arden sounds masculine to me.
Besides that, the
Elizabeth Arden cosmetics came to mind, the second I saw this name. The foremost main reason not to ever consider it, because I bet other people thinks that too, at first when hearing it on a kid. Whether it's on a boy or on a girl. And I think a boy would hate that growing up. On a girl maybe not so much, if she turned up to be a girly-girl, loving that connection and not a tom-boy, who wouldn't touch make-up at all (as me here).
