If my spouse and I have similar credit scores, can we both be on the same loan to qualify?

Yes, and with similar scores, both of you on the loan is usually the ideal setup. Being on the loan together lets you combine both incomes to qualify, and because your scores are close, neither one drags the other down. The mechanic worth knowing: with two borrowers, the loan is priced off the lower of the two middle scores. Fannie Mae and Freddie Mac price a joint loan off the lowest borrower's representative score, and FHA uses the lowest decision score, so a big gap between spouses sets the rate off the weaker file even with a stronger one right beside it. One nuance on the conventional side: for some qualifying-eligibility decisions the automated system now uses the average of the borrowers' median scores, but pricing still runs off the lower one. A big gap is when the math sometimes changes. Qualifying on the stronger spouse's income and credit alone, leaving the other off the loan while possibly keeping them on title, can be the cleaner call. We have done that where the lower-credit spouse also brought a complication like a business loss on their tax return. That is the exception. With two similar scores there is no penalty to worry about, so putting both of you on the loan gets you the full income without sacrificing pricing. Have a lender show you both scenarios side by side to confirm it for your exact numbers.
