I still have no clue what type of environment you are actually using, so
part of this is just guessing.

You can certainly modify and compile a single binary. If you have a
running system, you can deploy it separately by copying it to it's
proper location on the target system (e.g replace the last version with
the new one). sftp is your friend.

The internal structure of the firmware image depends on how it is built.
A Buildroot image contains at least a Linux kernel and a root
filesystem. Buildroot supports various formats, for example cpio,
tarball or bootable disk image. A mechanism for auto-deployment is not
included, normally you copy a file to a pre-determined location or use
dd to flash a device.
