Well, possibly. Firstly, the phone encryption system is Bitlocker. MS claims that a Bitlocker-to-go encrypted drive (or SD card), whilst such can only be made on a Pro or Enterprise edition of Windows, can be decrypted on any Windows SKU. Whilst I can confirm this is true for most Windows devices, my 930 does not have an SD slot so I cannot test on the phone. It may be that MS was not thinking about Mobile when they committed the rules to writing (surprise...). If so, look to file level encryption. Is there a file compression app for the phone that can handle encrypted archives? If so, that's often an excellent form of encryption.
