If the Kingdom of Sweden Explores into a land with Escalation, can a triggered action like Call to Guard get rid of that Explorer before the Escalation checks if a Dahan will be replaced?

Yes, but you can choose the opposite order if you want to lose the Dahan.
This only works because Sweden's Swayed by the Invaders Escalation checks how many Invaders and Dahan are present when that triggered action finally resolves, not when the land is Explored. (The Escalation technically happens in every explored land; it just doesn't do anything if the Invader & Dahan condition isn't met.)
