It can, but if you attempt to trade them to Gen 6, they will all come through as glitched pokemon (using ditto/mew/missingno is same result)
From the rules on the Catch'em All leaderboards : "The 3DS Virtual Console version is not allowed due to an error in how money manipulation is emulated."
Maybe you should read the rules before considering learning a new category ? 🤔
Thanks for clarification Cynda, I knew the glitchess for Mew/Ditto manipulation were still possible, but unaware it was not allowed.
A little late to the party, but if you were to make a route for 151 that did not include money manipulation, you could make a case to the moderator team to allow it. As it stands now though, the only route in use (the one in the Guides section) uses money manipulation, so it is not allowed
Also late to the party, but the money manip used in the current route should work fine on VC, IIRC it's only halving money after a wipe that sometimes gets messed up if you have a glitched money value. The current route only buys things while having "legit" money.
