That depends on your compiler.

Lambdas have been supported since GCC 4.5, Clang 3.1, MSVC 2010.

We are currently shipping GCC 4.8 for MinGW, so it should be fine.

For Android and iOS, you need to check what versions of the compiler are 
available in the SDKs and NDKs for those platforms. We don't ship the 
compilers. Apple keeps their Clang version quite up-to-date, even if 
completely branched off from the Clang mainline. That's not the case for the 
Android NDK though.
