Assuming you meant to add "in a place where traffic keeps right", I would
say no.

>How about on the right side of a dual carriageway?

Assuming you mean the right side of the right way of a dual carriageway in
a place where traffic keeps right, I would again say no, as this is the
same as the case above.

The way I understand it, cycleway=lane means bike lanes on both sides of a
two-way road, or a bike lane on the right or left side of a one way road
where traffic keeps right or left, respectively.

You need cycleway:right=lane on a two-way road where there is a cycleway
only on the right side. You need cycleway:left=lane for a one-way road with
a bike lane on the left in a place where traffic keeps right.

Prefix the value with opposite_ if bicycle traffic flows opposite to motor
vehicle traffic.
