Nope, not canon as such. Admittedly, all we have seen is duels with melee weapons, but Worf vs. Duras at least was fought with dissimilar swords. Duras opted for a two-handed, two-edged single straight blade there. And Worf often practiced dueling with just his short mek'leth. We have also seen various types of spear - and Worf in "Birthright" seems to be saying not just that the gin'tak is a weapon of war rather than a farm implement, but that it is still
being used for fighting.
Whether ranged weapons could be used for dueling, we don't know. But each side chooses its own weapons, it seems. Perhaps honor concerns discourage either side from picking a weapon that might prove too superior to what the opposition will pick, and thus subject the overarmed duelist to ridicule?
