Playing cards without a check in Pathfinder
Yes playing both cards outside of an encounter are allowed. From the Pathfinder Skull and Shackles rulebook (and probably the others as well as the rule hasn't changed) on page 9:


  Playing Cards
  
  Anyone can play a card whenever the card allows it. Playing a card
  means using a power on that card by revealing, displaying, discarding,
  recharging, burying, or banishing that card or by performing another
  action specified by that card.
