A wireless charger has no data transfer capability yet, so "no" for now. However if a USB port shows any sign of data transfer capability, it's blocked until you trust it.

Power starvation / observation attacks are passive attacks in a sense. They get their results by observing only.

..but...the article

[bayindirh]

The article is about a side-channel attack, where you don't transfer any data, but just observe something (in this case power draw from a wireless charger) to get some information.

In these types of attacks, you don't transfer any actual information, but guess something from observation.

There are more exotic attacks [0][1] which exploit the heat computers generate to exfiltrate data or time power starvation attacks.
