Most font licenses allow one to embed it into a document and then use that document as intended (to print, view...), but do not extend the license to the document recipient to extract the font and use it in newly created documents.

Using a common font like Times-compatible (metrics-wise) does help to an extent, but it can still fall off quickly with different ligatures, Unicode-combining character support etc. To be honest, I've never seen a Word document that looks exactly the same when opened on two Windows computers, even if those two computers should be roughly the same (corporate managed computers): I remember it used to be affected by print settings back in the day, but not sure what triggers it today.

Admittedly, I only use Windows computers and Word documents the last few days at work, as I've been in the Linux world for the last ~27 years otherwise.
