Could I use the Cat6 panel as part of a 10 Gigabit Ethernet link?

Potentially, yes, but Cat6 is not the straightforward answer for a full 100-metre 10GBASE-T channel.

Around 37 metres is generally the uncomplicated territory, with roughly 37–55 metres possible depending on the alien-crosstalk environment.

For a new full-length 10 Gigabit installation, Cat6A avoids a fairly convoluted collection of distance and interference caveats.
