Probably, but since you did not state what your laptop is, we can't make any guarantees.
If you have a bottom budget tier laptop with AMD, intel atom,or intel Celeron CPU then the CPU is bottlenecking things before the hard drive can. Thus an SSD drive upgrade will provide very little in the way of performance increase.
If your computer is running windows 10 then the easiest way to tell what your computer needs is to open task manager.
When you are performing tasks is it the CPU, memory, or disk that is typically pegged at or near max. Whichever one is most commonly at or near max is the first thing to address.
FYI the CPU is not replaceable in almost all laptops, so if the CPU is always pegged then you should just be saving up for a better laptop.
