Does the Samsung 45W Power Adapter Fast-Charge the Lenovo ThinkPad X1 Carbon Gen 12?

Yes, but the charger is the limiting factor — only 45W via PD PPS, below the device's 65W ceiling.

Both sides speak PD PPS, but the Samsung 45W Power Adapter's port tops out lower than the Lenovo ThinkPad X1 Carbon Gen 12's 65W ceiling, so you get 45W instead of the device's absolute max.
