With the recessed cans I’ve used it would be possible. I’ve taken apart the can’s body by removing 4 screws. From there you can remove the electrical wire that leads to the box where the connection is ultimately made. If there is enough length in that wire, you can pull it through the can’s hole in the ceiling, repair the drywall, leaving the wire stubbed out through the ceiling and install your new track lighting using the recessed can’s old power source.
If the wire isn’t long enough, you can add more length by connecting whatever extra length you need to the existing wire. This connection must be made in a box with a cover, mounted inside the ceiling cavity. From there, you can place the track light power transformer where you like, within reason.

It won’t look right.
it won’t look right, however it can be done.
it won’t be safe or up to code
why not just get another track light fixture that suits your needs
they are not very expensive
