Nope, unless mkfile is is guaranteed to give you contiguous space:

# uname -a
SunOS vmsol8 5.8 Generic_108529-05 i86pc i386 i86pc
# mkfile 100m a.a
# swap -a /a.a
# swap -l
swapfile             dev  swaplo blocks   free
/dev/dsk/c0d0s1     102,1       8 1048936 1048896
/a.a                  -        8 204792 204792
