I have removed these packages:

 

iw wireless-regdb rfkill hostapd  (no wifi)

ntfs-3g btrfs-progs (filesystems I don't use)

stress iozone3 (benchmarks)

qrencode (huh?!)

alsa-utils (no sound)

ifenslave (not needed I think)

sunxi-tools (different processor)

command-not-found (don't want it)

 

And then apt autoremove to remove corresponding libraries etc.

If you need to free up space try installing localepurge to remove unwanted languages from docs and man pages and such. When every megabyte counts this will help a lot without having to remove any programs. Select no when asked about the exclude path option to process already installed stuff. If you select yes it will only strip the languages from newly installed stuff.

If you're comfortable with using the armbian build system to build your own image, there is a BUILD_MINIMAL flag to make an image with minimal packages.
