For questions like this, it's always best to look at the authoritative
source for the format of various OpenPGP data - RFC 4880 :)  From the way
I read section 5.5.3 (Secret-Key Packet Formats) and then Section 3.7.1
(String-to-Key (S2K) Specifier Types) it would seem that the answer to your
question is yes, the S2K count is stored in the secret key packet.

G'luck,
