To answer the original question:  Yes, it is possible.  

As the other respondents have indicated, you would be facing some
increased risk and the question is whether the increased risk is an
acceptable trade-off for you.

If I really, really needed the performance, I'd put the swap on 2
striped raid0 drives.  I'd probably mount every partition except /var
and /home/workplace read-only though.
