Sorry - I missed your question before. The answer to your question is fundamentally, yes. The source code from the Linux-NTFS project may for example compile and run on Solaris. Whether significant changes would be necessary to the code I don't know - you could ask the project authors.
In any event, there are always alternative solutions to this kind of problem. Most server OSes "in the real world" should not be coexisting with other OSes as multi-boot systems. You would normally build separate systems and then connect them via NFS, FTP, Samba, etc.
