I tried extending my rift cv1 with a 3m usb3 extension and hdmi extension. It mostly worked, but I'd occasionally get blackscreens or visual glitches. I think the total 7m was just at the edge of the limit of the hdmi signal strength. You might need to get an active hdmi extension depending on your gpu (i have a 1070 ti). The usb connection seemed fine, didn't have tracking or sound loss.
