Can "13 billion" yr old planet actually be younger?

Is there any reasonable chance that the planet formed significantly
later than this, and was subsequently captured by the stellar pair
through fairly well established 'encounter' dynamics within GCs,
where stars (and presumably planets) can exchange partners on
a much shorter time scale than in the disk star population?

Does M4 pass through the galactic disk? If so, could it have captured a much
younger gas giant during an interaction with a younger star while the core
of M4 was passing through the thin disk?
