Sure you can put her in a large kennel...you just have to call it a playpen :P That said, solutions not involving physically penning kids in are better, especially as they improve their ability to get out every day. Can you try something like 'sit on your bed and read/listen to this audiobook/do this craft until the timer goes and then you get <reward>'. Start with short times and make them longer (eg a sultana for every minute at the start). I can get my toddler to stay put on a mattress for quite a while now during 'nap' time. I started with short times and combined rewards for staying put (stickers, stamps, cuddles, high fives etc...I never had to resort to m&ms, but I bet they'd have worked) with disincentives (stern voice and manner, physically putting her back or holding her in place, timeouts) for leaving the space.
Rather than jumping on the bed, we have an old cot mattress that we use as our 'trampoline' for getting energy out (so we don't have to break the no jumping on the bed rule).
I second the advice to just go for your walk during a time when kids are awake. Let your hubby know beforehand (On Mon I'll be going for a walk at 6pm), do what prep you can (feed the baby, have toddler's dinner ready to go) and leave him to it. You may also find it works to leave the toddler and take the baby: babies are much less likely to interfere with your walk and in a carrier or a pram can add some extra to your workout and hubby will find just the toddler easier to deal with than both.
