ELI5: If two very different species share the same amount of chromosomes and we would use artificial insemination to overcome physical limitations, could they breed?

According to [this](http://en.wikipedia.org/wiki/List_of_organisms_by_chromosome_count), humans, reeve's muntjacs and sable antelopes share the same amount of chromosomes.

I extend this question, as I have searched reddit before and read some answers already. But I noticed some holes in it.

One limitation is incompatibility, but we covered that as all of the named animals have 46 chromosomes. In theory they should be compatible, or am I wrong with this?

Another limitation is sperm dying off due to chemical differences in different species uteruses. So why couldn't I inject sperm directly into an ovum, like it is done at everydays artificial insemination? We have the technology, why not trying it?

Before you go all "but ethics!!!!!", if you feel better about it think about a cow and a goat, both have 60 chromosomes.

If you are still in doubt to answer my question properly, think about barely and pea, two different herbal species sharing 14 chromosomes.

If you are still in doubt, I guess you can't answer my question anyway.
