I can be telling nothing but speculative stuff here, but...

Nagios A, B & C, running active checks, and sending results passively to
some other Central Nagios, let's say... Nagios X.

On Nagios X, you will need to configure 3 services, one for each
Distributed Nagios servers (A, B and C). Then you can configure only
Nagios X to send notifications about host D going down, after made sure
with a fourth active check made by Nagios X, after getting stale results
from the distributed servers.

It's how it came up to me, but other people can have other solutions
aswell.

Like configuring service dependencies, or service escalation, whatever
solution you get. IMO, Nagios could do the job.

cheers.
