you can't have 3-way sync with mbsync.

the classic star config (each device syncs from the server and 
notmuch'es independently) works fine, but that would leave the archive 
inaccessible from the laptop, except if you configure a separate channel 
for that.

you could use an additional always-on device with an IMAP server as a 
proxy to "chain-sync" from. that device would hold the entire box 
including archive, and mbsync itself to the real server. your pcs would 
sync only from that device (whose imap port you'd have to make 
accessible from the outside, be it via port forwarding or a vpn). a 
raspberry pi or the home router itself (with custom firmware and an 
external hdd) should do.
