Can my ally and I share control of battlefields?

No, you and your ally can never have units at the same battlefield. A maximum of two players can have units at a battlefield. Those players must be opponents, and a combat will result.

If I use Hostile Takeover to take control of my opponent's only unit at a battlefield, will there be a showdown? Will it be a combat?

You'll start a noncombat showdown. A gap exists in the current rules, but we believe starting a noncombat showdown is the least disruptive way to handle this scenario.
