You certainly can. LabVIEW Real-Time functionality is really not much different than what you can do on Windows. The only difference being that you can now assign priorty and timing to your execution loops; essentially, you have determinism with RT whereas with Windows, you never have a guarantee.
Thus, in regards to calling a dll, you can perform this the same way you would in LabVIEW for Windows. Here's a KnowledgeBase article on how to do this if you're not already familiar.
