Yes and No
I am not a dev member, but I had the same question.
The mined keys are special. they have specific angles and the miner is programmed to find this special keys. If you create a wallet with initially no VFC in it you have a wallet that is not minable by official miner.
However one can modify miner to mine not these special rewarded keys (I did this modification just for testing) so the modified miner, mines keys but not rewarded ones. Now technically this new miner can mine a personal wallet like yours but the probability is very vey low for a specific wallet and is very low for any non-zero wallet. Yet it is possible. It depends on how many non-zero wallets are available in the chain.
So my suggestion for you and myself is to have more than one wallet (Just in case )
