Yes- it appears to be possible to install and run Junos 9.0 with 256MB
CF in LAB environment (system is M320 w/ RE-4.0):

I also upgraded M7i machine which has less DRAM installed into RE.
Unfortunately this one doesn't have CF at all ... ;)

Both machines work well in our LAB. This means - routing tables are
small; very few MP-BGP prefixes, etc.
However it remains questionable if this is stable for production
networks and how will behave Junos 9.0 with small CF cards and DRAM
(IGP, many BGP peers and so on). And I doubt you will receive J-TAC
support in case of need.
My advice is simply upgrade your RE's hardware accordingly.
