It depends on what type of connector/slot you are using for internal wifi.
A traditional mini-pcie slot will have provisions for USB or PCI Express x1 interface.
A traditional M.2 slot will have similar provisions.
Depending on the make/model of your current wifi card it might use USB or PCI express.
If it is USB, the answer is no.
If it uses PCIE, then you have a chance.
If its Mini-Pcie, then its a Disk-on-Module, or DOM you want to buy.
If its M.2, then you can use a M2242 type of SSD.
Again, it all depends on what your research comes back with when you see the specs for your current wifi card.
