Yes, you can.

When this Digimon digivolves onto a Tamer card, does the Tamer card’s <Security> effect become an inherited effect?
No, Tamer cards' <Security> effects aren't inherited effects. Some Tamer cards do have inherited effects, and those can be activated when such cards are placed in digivolution cards.

After a Tamer card ends up in this Digimon's digivolution cards, is that card affected by effects that trash digivolution cards?
Yes, it is. However, if the effect specifies Digimon cards, Digi-Egg cards, or any other type of card that isn't a Tamer card, it can't be targeted by that effect.

If I digivolve this card on top of a Tamer card, do I still get the digivolution bonus?
Yes, you do. Even if you digivolve using a Tamer card, make sure to draw 1 card as the digivolution bonus.

Can I attack the turn I digivolve this card on top of a Tamer card?
Yes. Digivolution doesn't count as “playing” a card, so you can attack that turn.

I play a Tamer card, then digivolve it into this Digimon. Can I then attack with that Digimon during that same turn?
No. Since it's the first turn the Tamer was played, the limitation for attacking on the first turn a card is played still applies.

If I've digivolved this card on top of a Tamer card and the Digimon is deleted, what happens to the Tamer card?
It’s trashed.
