I don't see why not. Talk to your cadre. I'd be certain that is what I want to do though prior to having that conversation. If you are on scholarship and are at least a sophomore you may (most likely will) be liable to repay any funds you received via the scholarship.
NOTE: I'm assuming LOA means Leave of Absence in this context. I am further assuming you are studying abroad or something like that. If you are on some form of "medical" leave then perhaps you should wait until your "return" as a medical DQ might eliminate any repayment.
Hope this helps!
