Yes, but ionic bonds are almost always between the cation and anion whereas covalent bonds are shared between atoms. Ionic bonds can have covalent character while covalent bonds can have ionic character which is why Dr. Lavelle didn't specify if the bond is ionic or covalent when the difference in electronegativity is between 1.5 and 2.
It is possible, however the differentiating factor between the two types of bonds comes down to their physical and chemical properties. For example, covalent bonds are typically between two nonmetals whereas ionic bonds are typically between a metal and a nonmetal. You could also observe their difference in electronegativities.
Covalent bonds have ionic characteristics if they share their electron unequally (if one element is more electronegative than the other, but not enough to become completely ionic). This is called a polar covalent bond. One side of the molecule is more positively charged and one side is more negatively charged because of this unequal sharing of the electron, which causes the molecule to have charges just like an ionic bond.
