Not exactly. It was not specifically designed for detecting life, but it has a lot of instruments that could provide enormously strong evidence for life. For example, if you took a pile of mulch and put it through Curiosity's SAM instrument suite you could look at the data coming out of it and go "yup, that's a bunch of wood chips, unquestionably". But that would require quite a bit of luck. If there are only extremely small amounts of materials of biogenic origin Curiosity is unlikely to be able to definitively identify them.
