That's also assuming the DMA attack isn't confined to a non-net/non-firewall/non-dom0 VM. A single compromised AppVM that isn't involved in the shared network connection shouldn't affect the laptop (but could scrape info and tamper with anything you do in that VM, which might have cascading effects with any credentials used elsewhere). But if dom0 or sys-net/sys-firewall (or whonix-gw or any other netvm/proxyvm) is affected by the DMA attack, the rest of what I said should apply.
