I think it's possible using swsusp on Linux _only_ if you do NOT share any
partitions between your OSs.  One of the 'states' that is remembered is the
state of your file system.  My linux system still mounts (writeable) a FAT32
partition.  If I suspended and restored into Windows, I'd end up corrupting that
partition on the next restart of Linux.
