Can さくじつ and きのう be used the same way?
It depends on the context.

さくじつ and きのう both mean yesterday (and the same Kanji 昨日 is used for the
words). A major difference in their usage is that さくじつ is almost always used
in a **formal** context (written and spoken), while きのう is often used **both**
in formal and informal contexts (written and spoken): Using さくじつ in a casual
conversation seems weird. You can hear きのう not only in a casual conversation
but also in the news.
