Yes you can, but you have to use the right functions.

Note that a file in gzip format includes some zlib-encoded data, after  
a header, but it's not plain zlib-encoded data.

This works:

$ echo hello > test
$ gzip test
$ csi -q
#;1> (use z3)
; loading /usr/local/lib/chicken/3/z3.so ...
#;2> (read (z3:open-compressed-input-file "test.gz"))
hello
#;3>
