Generally speaking, the answer is a definite "No".

However, speaking of POV-Ray in particular, you can abort a render, and resume
it later using the +C command line option (make sure all other options are the
same).

Make sure to try it on a quick render first though ;). Also make sure you
specify exactly the same parameters aside from the +C option.

Note that in the POV-Ray 3.7 beta, +C may not yet work properly when using
certain features; for instance, Radiosity will probably require you to
explicitly specify a sample cache file using the new "Radiosity_File_Name",
"Radiosity_To_File" and/or "Radiosity_From_File" options for now.

How about one of those energy-saving standby modes? Maybe suspend-to-disk is
sufficiently close to what you want. (Don't know whether Linux supports it; but
given that Windows does, Linux should be perfectly capable of such stunts as
well, right? :P)
