Technically, ... ? As in what we know about 2nd and mixed conditionals? No, the first sentence is awkward as a 2nd conditional. It should be a mixed conditional PAST-PRESENT:

Note, in American English (AmE), the present perfect is merging with the past simple, which produces sentences like the one you have:
- If I took the bus, I would be home now.
I doubt AmE speakers would interpret the sentence above as a 2nd conditional. The reason being, the Result (i.e., I would be home now) refers to the present, not the future, and for that reason it would be interpreted as a mixed conditional.
